Definitions
- the invention relates to the field of clinical diagnosis and / or noninvasive therapeutic monitoring. More particularly, the invention relates to a microscopic device for collecting molecules of biological interest by contact, which does not require ablation or biopsy, and whose architecture is such that its insertion does not cause damage to the body. surrounding tissue.
- the invention is particularly suitable for proteomics or genomics.
- the invention also relates to a method for determining the protein composition of the different layers of a tissue.
- this method is suitable for mapping tumors, for example in the brain.
- the method of sampling target molecules is crucial.
- the existing tools for performing molecular analysis are all based on the principle of biopsy, that is to say on the collection of more or less whole cells or tissues, which will be analyzed ex situ. These techniques therefore alter the biological integrity; moreover, they can not always be used, all the more so since the very insertion of a sampling device must be minimal in certain regions, in particular for example in the brain.
- the invention in one of its aspects aims to overcome the disadvantages of existing sampling devices.
- Molecular imprinting is a new approach. It consists of not extracting tissues from the area of interest, but simply affixing them the sampling tool. By contact, on a suitable associated surface, many molecules, such as proteins, become trapped on the tool and can then be desorbed and analyzed ex situ.
- the invention therefore proposes to use simple contact for the collection of molecules of biological interest: a tissue imprint is obtained on a device according to the invention, and the molecules thus recovered in a capture zone of the device can be analyzed. In particular, as the size of the device, usually plane, is reduced, the developed area of the capture area of the device according to the invention is increased so that the amount of trapped target molecules is sufficient to allow effective subsequent analysis.
- the sampling device thus comprises a support having at least one molecular capture zone on one side.
- the capture zone is such that its developed surface is at least three times larger than its surface when viewed from above; the ratio between developed and projected surfaces can reach a factor of twenty or more.
- the device according to the invention is of small size and in particular "microtechnological”, that is to say that its microscopic section, less than 1 mm ⁇ 1 mm, can be achieved by methods used. in microtechnology.
- microtechnological it should be understood that the insertion section of the device according to the invention does not exceed 1 mm 2 and, preferably, it is included in a cylinder of diameter 800 ⁇ m, by For example, it has a parallelepipedal section of the order of 300 to 600 ⁇ m over 100 to 300 ⁇ m.
- the support may include another capture area on a face opposite to the first.
- the device according to the invention comprises, on one or both faces, several stepped capture zones, that is to say separated by zones of interval preferably defined physically.
- the device is breakable between the different capture zones.
- separation means such as notches obtained by partial etching of the support, are present in the gap zones.
- Capture areas include a bottom wall, which may delimit a cavity.
- the bottom wall can serve as a base for the introduction of microbeads, which are maintained by a semi-permeable membrane, and / or have protrusions.
- microtechnological techniques silicon etching for example, or plastic molding are possible, to create for example organized networks of square, hexagonal or octagonal columns of 3 to 50 microns or 80 microns, for example between 5 and 20 ⁇ m, side and height between 10 and 400 microns, for example of the order of 50 microns.
- the capture zones are functionalized, that is to say that the walls of the support and / or the microbeads are associated with markers, which may carry affinity functions of the molecules of interest or be used. for saturation of the majority species, in which case the use of beads having ligands specific to the majority and minority species is preferred.
- the device according to the invention is preferably associated with a handling rod and a guide sleeve which allow to position it accurately within the tissue to be analyzed.
- the sleeve may comprise means which make it possible to put the capture zones in contact with the surrounding medium only when the device is in place.
- the invention provides a method for performing differentiated mapping or analysis according to the depth of the target area. A device having several staged capture zones is inserted into the tissue to be analyzed, a contact sample is taken, and the molecules taken by the different capture zones are analyzed separately.
- the capture zones can be separated from each other by section of the device, or the support of the zones of capture can be used in measuring equipment.
- Figure 1 shows a contact pickup system according to an embodiment of the invention.
- Figure 2 shows an embodiment of a capture area for a device according to the invention.
- Figures 3A and 3B show, in section, another embodiment of a capture zone for a device according to the invention.
- FIG. 4 shows another embodiment of a capture zone for a device according to the invention.
- Figure 5 shows a functionalization of the device surface.
- Figures 6A to 6C show different types of ball functionalization.
- Figures 7 show different embodiments of means for separating the capture areas of a device according to the invention.
- Figure 8 shows a method of using a device according to the invention for mapping.
- Figure 9 shows the results of an analysis by a device according to the invention (B) and functionalized (A).
- a sampling system 1 may comprise a guide sleeve 2, for example a catheter: the guide 2 makes it possible, among other things, to define the passageway for the sampling device. In particular, it may be put in place, possibly under optical or radiological control, beforehand in the target zone 3, for example a tumor or a tissue, in vivo or already removed, for example by biopsy.
- the end portion 4 of the guide 2 is provided with closure means 5 which protect the sampling device 6 during its insertion and allow to bring it into contact with the tissue of interest 3 once in place.
- the sealing means 5 are preferably located along the longitudinal axis of the guide 2, the distal end of which is closed.
- the sealing means 5 may for example be a rotary or sliding window, or a partially absorbable membrane.
- the sampling device 6 advantageously comprises a handling rod 7, the length of which depends on the use and the depth of insertion, and which can slide in the guide 2.
- the end portion 8 of the rod 7 is intended to to the sample itself.
- the guide 2 and therefore the manipulation rod 7 have a very small diameter so as not to alter the tissue 3, and allow non-invasive procedures in a patient.
- the rod 7 may have a diameter restricted to a few millimeters, or even 100 microns; the guide 2 has an outer diameter close to the diameter of the rod 7.
- the rod may, for example, be of surgical stainless steel.
- the amount of fluid removed must be sufficient to allow the extraction of information on the tissue nature.
- the use of a simple needle 7 of small diameter does not allow a subsequent efficient analysis because of the small amount of target molecules trapped on its surface, which is reduced even if machining is performed.
- the sampling system 1 can be used without restriction, in particular also in the brain, and therefore the device 6 is included in a cylinder with a diameter of the order of 995 ⁇ m or less.
- the end portion 8 of the sampling device 6 has at least one capture zone 10, the developed surface of which is very thin. greater than the normal surface, from 3 to more than 20 times, which reduces the size of the device 6 while maintaining the sample in adequate proportions.
- the sampling device 6 thus comprises a support 12 which is preferably independent of the handling rod 7 at the end of which
- the support 12 is preferably made of a biocompatible material, in particular silicon as specified below; the different elements making up the guide sleeve 2 are also compatible with a biological and / or medical use, for example in gold or plastic, ....
- the support 12 may be of any shape, but advantageously it is plane, in the form of a plate, as will be apparent from the description of the manufacturing processes. Whatever the case, it is possible to define on the support 12 a first face 14 and a second opposite face 16: in the case of a non-planar support 12, the terms "face” and “opposite face” designate portions of the outer surface of the support
- the faces 14, 16 are included in a support 12 which is of the order of 1 to 3 cm long (in the direction of the rod) on a width from 300 to 800 ⁇ m, for a thickness of the order of 200 to 400 ⁇ m.
- the first face 14 of the support 12 is provided with a capture zone 10; it is preferable that the capture zone 10 leaves a proximal end portion 8 sufficiently long, for example from 2 to 5 mm, to allow easy attachment to the rod 7.
- a preferred embodiment P relates to a support 12 rectangular silicon of dimensions 300 ⁇ m ⁇ 600 ⁇ m ⁇ 2 cm, the structured zone 10 starting at 3.2 mm from the edge secured to the rod 7.
- capture zones 10a, 10b, 10c, 10d are present on the face 14 of the support 12, separated by zones of interval 18.
- four capture zones are present , but it is clear that their number depends on the use, in particular the size of the device 6, the size of the target zone 3 and the concentration of molecules of interest in this zone 3, as well as the surface area. developed capture areas 10 and the manufacturing process.
- the zones of interval 18 may be only "virtual", that is to say that the capture zones 10 are a priori confused at the macroscopic level, but that means make it possible to distinguish them at the microscopic level. or even to separate them.
- capture zones 20 are placed on the second face 16.
- the second capture zones 20 are in alignment and in opposition with the first zones 10.
- the second capture zones 20 may be identical in nature and geometry to the first zones 10, or different, as shown diagrammatically in FIG. 1: the various embodiments presented below may be combined .
- the developed area of each of the capture areas 10, 20 is greater than three times the planar area of the capture area 10, 20.
- An embodiment is shown in Fig. 2.
- the capture zone 10 comprises a bottom wall 22.
- the bottom wall 22 may be located on the support 12, or may delimit a cavity therein (see FIG. 4).

- the height of the protuberances 24 is identical to the depth of the cavity, but it is possible that they are salient.
- the surface of the support 12 is uniform, preferably plane, with the exception of the capture zones 10, and any separation means
- the developed area _S of the capture zone 10 is therefore equal to the surface _s of the bottom wall 22 to which is added the surface of each of the lateral walls of the protuberances 24.
- the surfaces satisfy the relation: S> 3.
- the factor 3 may advantageously take the values 5 or 10 for example.
- the protuberances 24 can take any desired geometry, for example square columns or hexagonal section. Preferably, the protuberances 24 are arranged in a regular manner, for example in a square or hexagonal mesh network. According to the preferred embodiment P, the surface pattern is in the form of octagonal spikes 24 of silicon, 50 ⁇ m high and 20 or 80 ⁇ m wide.
- the support 12 is made of plastic, it is possible to use injection techniques or hot stamping ("hot embossing"), which allow to obtain by replication additional mold parts previously produced. It will thus be possible to produce protrusions 24 of 20 ⁇ m on a side, at a height of 50 ⁇ m at low cost, on a support 12 made of polyethylene, or poly (methyl) methacrylate (PMMA), or polycarbonate, or polydimethylsiloxane (PDMS), or parylene, or Teflon TM; an option is also to deposit one of these materials, including parylene or Teflon TM, on a plastic surface, or even metal, to make it biocompatible.
- hot embossing injection techniques or hot stamping
- microtechnology techniques For example, the method described with reference to FIG. 7 of document FR-A-2 846 957 may be used; the process described in this document is however, simplified because only the support 12 is machined: there is no formation of supply channels and / or hood sealing. Such a method makes it possible to obtain protuberances 24 of 5 ⁇ m per side over a height of 100 ⁇ m on a support 12 made of silicon.
- the protrusions 24 can be 5 to 20 microns (even if sizes up to 80 or 100 microns can also be made in this way) aside for 50 to 400 microns in depth; the machining of the support 12 is such that at the end of the process, the device is biocompatible.
- a support 12 of silicon is oxidized to be coated with SiO 2 , biocompatible behavior similar to glass.
- microbeads 28 are commonly used in microbiology; they conventionally have a diameter of the order of ten nanometers up to a hundred microns, and may be composed of glass, porous or not, which allows them to be functionalized and remain biocompatible. According to the embodiment of the capture zone 10 and the positioning of the protuberances 24, as explained in the document FR-A-2 846 957, it is possible to achieve an alignment of the balls 28 in the spaces 26 between the protuberances 24 ( Figure 3B), which facilitates the quantification of the developed surface.
- the spaces 26 between the protuberances have a width less than 50 microns.
- any other embodiment is possible, including random packing. It is also possible to size the spaces 26 so that first balls 28 are precisely located and second balls 28 'of smaller diameter can then be put in place (Figure 3A).
- the microbeads 28 increase the developed area of the capture zone 10 significantly. It may be advantageous in this case not to have protrusions 24, but capture areas 30 composed of cups 32 filled with balls 28, as shown diagrammatically in FIG. 4.
- the cups 32 of the capture zones 30 can be made by example by microtechnological etching of the support 12, or by transfer of a mesh of walls 34, or by molding plastic material. They are then filled with microbeads 28, advantageously calibrated.
- porous membrane 36 In the presence of microbeads as in FIGS. 3 and 4, it is advantageous to maintain the balls 28 in place by a porous membrane 36.
- the porous film 36 is chosen so as to leave the molecules of interest to migrate within the capture zone 10, 30. It is possible to use commercial polycarbonate filters with a porosity of less than 1 ⁇ m which can be glued to the cavities by screen printing (for example Dynamask TM, from the Dynatech company) ), or dry films of photoresist (such as Ordyl TM from Elga) which is photolithographically insulated to achieve porosity; this technique is more suitable for balls 28 with a diameter greater than 1 ⁇ m.
- the modified support will undergo one or more post - silanization reactions until it is obtained. the latter.
- the coupling function A corresponds to the set of existing organic and mineral functions such as the functions: CH 3 , alkenes, alkynes, aryl derivatives, halogens (Br, Cl, I, F), organometallic derivatives, alcohols, phenols, diols , ethers, epoxies, carbonyl derivatives (aldehydes, ketones, carboxylic acids, carboxylates, esters, amides, acid chlorides, acid anhydrides), nitrogen derivatives (Amines, nitrates, diazos, imines, enamines, oximes, nitriles), phosphorus derivatives (phosphines, phosphites, phosphates, phosphonates), silicon derivatives, sulfur derivatives (sulphides, disulfides, thiols, thioethers, sulphones, sulphites, sulfates, sulfonic acids, sulfonates, azasulf
- a spacer group E, used between the two functions A, Y of the coupling agent, makes it possible to confer particular properties on the film obtained by silanization.
- the group E is chosen from among the radicals making it possible to obtain an organized monolayer: a long chain alkylene radical E allows interchain interaction (among the radicals E of the alkylene type, those having from 8 to 24 atoms are particularly preferred.
- a radical E comprising two triple bonds -C C- allows crosslinking; a radical E comprising a conjugated aromatic chain confers nonlinear optical properties (for example, mention may be made of the phenylene-vinylene and phenylene-acetylene radicals); a radical E of the pyrrole, thiophene or polysilane type confers an electronic conduction; a radical E of the heterosubstituted polyaromatic type confers photo / electroluminescence properties (for example, mention may be made of quinones and diazo compounds); a group E of the alkyl or fluoroalkyl type, in particular an alkyl or fluoroalkyl group having from 3 to 24 carbon atoms, makes it possible to use the layers obtained by chromatography or electrophoresis. Regarding the functionalization of the beads, the same principle is used.
- the surface ester functions located on the tool will react with functionalized beads bearing primary hydroxyl function. After the immobilization of the balls 28, the tool has a hydrophilic developed surface (FIG. 6A).
- n types of beads 28 each carrying a specific ligand are prepared in n specimens n types of beads 28 each carrying a specific ligand, to mix them, and then to fix them to the tool via ligand Y (NH 2 for Figure 6B).
- Another option is to mix n specific types of ligands and fix them on a tool previously functionalized with beads (FIG. 6C).
- the sampling device 6 has several capture areas 10i (see FIG. 1), it is possible to use the same functions on each capture zone, or to perform a spatial differentiation, for example by the known localized spotting ("spotting”) for DNA chips.
- the supports 12 may be divisible for each of the preceding embodiments.
- the gap zones 18 between the capture zones 10, 30 are provided with separation means.
- notches may have been etched together with the production of protuberances 24 and / or walls 34: FIGS. 7.
- the gap areas 18, 34 can then be easily cut.
- Different embodiments can be envisaged: for example, it is possible to carry out a cleavage primer 42 by etching the support 12 on the face 16 opposite to the face 14 comprising the capture zones 10, by mask and etching for example (FIG. 7A ). It is also possible to make this notch 44 on the "front" face 14, or to choose, for example, an isotropic chemical etching, for example KOH (FIG. 7B).
- the zones of interval are composed of walls 34. It may be desirable in this case also to define notches cleavage 46 on the rear face below the walls 34: FIG. 7C.
- capture zones 10, 20 are present on each face 14, 16, it is possible to position separation means only on one of the faces (FIG. 7D), or both (FIG. 7E).
- Two embodiments can be noted in this regard for the devices comprising capture zones 10, 20 on each of their opposite faces 14, 16: a support 12 (FIG. 7D) or bonding of two supports 12, 12 '(FIG. 7E ).
- notches 42, 44, 46 can be used interchangeably and in combination.
- a silicon wafer 100 mm in diameter is machined to obtain 142 end devices after cutting.
- the support 12 made of silicon is advantageously marked: In particular, the name of the device, alignment crosses, cutting marks, etc. are engraved, for example at 500 nm, by photolithography with a mask and dry etching.
- the rear face undergoes a similar treatment (photolithography with mask aligned with the previous one, dry etching of 5 to 10 ⁇ m, removal of the resin from the mask) to form the notches 46.
- the front face is then drawn and etched for microstructuring, with photolithography with aligned mask, 50 ⁇ m deep dry etching and resin removal.
- the surfaces are then prepared to allow their biological and / or medical use: in particular the polymer (for example C 4 F 8 ) formed on the flanks of the cavities during etching is removed, by total deoxidation, followed by wet oxidation. over 100 nm, then complete deoxidation; a final SiO 2 layer is obtained by wet oxidation over 500 nm.
- the guide 2 is first put in place, preferably under control in the target zone 3; the support 12 is glued at the end of the rod 7.
- the rod 7 is inserted into the guide 2, under optical control also to ensure the accuracy of its positioning, and in particular to determine the areas A, B, C, D of the tumor 3 corresponding to each of the capture zones 10a-10d.
- the closure means 5 are open, and the sampling is done by apposition; no manipulation of the device itself is not necessary, the contact area of the capture areas 10 being directly accessible (without cover for example). This also allows a miniaturization of the assembly, including the support 12.
- the closure means 5 can then optionally be closed.
- the rod 7 is then removed from the guide 2, the support 12 is detached, and the capture areas 10a-10d can be analyzed. Two approaches to the treatment of the sample taken can be implemented during the analysis:
- the device 6 is breakable, and each zone 10a-10d is treated independently.
- the support 12 is broken and the different zones 10a-10d are introduced into washing and extraction tubes 50a-50d.
- the molecules A, B, C, D thus extracted can be stored in a data bank and / or deposited on a bar for analysis, for example a Ciphergen® bar used in particular to perform a mass spectrometric analysis for a proteomic analysis. like SELDI-TOFF®.
- the support 12 itself which serves as a substrate for the final analysis device 60, for example by laser assisted direct desorption. Whichever approach is chosen, one can obtain a map of the tissue of interest, and Protein composition versus depth in the target area 3.
- the sample is not very invasive: in particular, the apparent diameter of the device 6, and even of the system 1, is reduced, in particular to a few millimeters, preferably 1 mm, while retaining a strong surface developed to capture enough target molecules;
- the sample is not aggressive: it is done by contact (or "apposition") without tissue section 3; - The portion of the machined device and actually used for sampling is reduced and covers only the support 12, which can be associated with a low cost manipulation rod 7;
- the machining of the sampling portion 12 is reduced to the manufacture of the contact areas 10, 20, 30, without other mechanical elements or additional steps of sealing or gluing;
- the large developed area of the capture zones 10, 20, 30 compensates for the miniaturization and allows reliable analyzes
- the device 6 can be used in operative procedure in vivo or post-operatively, or in vitro on a tissue removed and requesting molecular analysis; the presence of staged capture zones 10a-IOd makes it possible to analyze after imprint the distribution of the molecules of interest in the sampling zone 3;
- each capture zone 10, 30 may be functionalized according to the targeted molecules and / or the type of final analysis (genomic, proteomic);
- each capture zone 10a-10d can be separated from the others and be analyzed by a specific technique
- the support of the device 12 may be compatible with any subsequent analysis equipment, for example it may comprise a specific matrix for mass spectrography;
- a mapping according to the depth axis of the zone 3 analyzed can be established according to the successive active zones A-D differentiated along the device; the stereoscopic operating method indeed makes it possible to precisely guide the device 6 and to know exactly which A-D region has been probed.
- the previous device P (Si support 600 ⁇ 300 ⁇ m 2 , with 24 octagonal protuberances) was silanized and then functionalized to give the carboxylate function. Indeed, physiological pH, biological systems including proteins are naturally charged; ionic interactions
- the acid function is protected in the form of a methyl ester after reaction of undecenoic acid with sulfuric acid and methanol; the incorporation of the silyl group is carried out conventionally by a hydrosilylation reaction.
- a methyl ester of 10-undec-1-enoic acid is manufactured to form the methyl ester of trimethoxysilylundecan-10-oic acid by the following method: - A solution of undecenoic acid ( 98%) (10.47 g, 11.5 mL, 56 mmol) dissolved in 500 mL of methanol is treated with concentrated sulfuric acid (12.88 g, 7 mL, 131 mmol, 2.3 equiv). . The reaction is carried out at 0 ° C. for 4 hours.
- the hydroxylation of the silicon substrate coated with a thermal oxide layer of 500 nm is carried out in a 3.5 M sodium hydroxide solution for 2 hours, with a silanizing solution of concentration 10 -2 M in anhydrous trichlorethylene, the silanization reactions being carried out at a controlled temperature of 20 ° C. for 24 hours.
- the modified support is contacted with a solution of aluminum iodide to release the carboxylic acid function, which in turn will react with an aqueous sodium hydroxide solution to give the corresponding carboxylate function.
- This device was used for mass analysis on a brain tumor (glioma), obtained after excision.
- the fabric is affixed to the tool and after rinsing and depositing the matrix, the analysis is carried out directly on the surface.
