Technical field
The present invention relates to a kind of co-detections of tumor markers in benign chip apparatus suitable for women physical examination examination purposes, belong to analysis test neck
Domain.
Background technology
Tumor markers (tumor marker, TM) refers in the generation and breeding of tumour, is produced in itself by tumour cell
Raw either reacted by body tumour cell and produce, reflection tumour exist and growth a class material, including protein,
Hormone, enzyme (isodynamic enzyme) and oncoprotein etc..The tumor markers in blood samples of patients or body fluid is chemically examined, can be in cancer screening

Index is surveyed, tumor markers joint-detection, the complementary tumor markers group of several sensitivity of reasonable selection, specific performance can be carried out
Into best of breed, joint-detection is carried out.In general the joint-detection of tumor markers can improve the accuracy to diagnosing tumor.
Only with regard to Diagnostic Value of Several Serum Tumor Markers its joint-detection background of related itself general picture or overview for, may refer to
Lower Chinese invention patent application case：CN200410041175.3、CN200510026780.8、CN200610040051.2、
CN200910064647.X。
Only for the microfluidic chip technology overall general picture of itself, famous micro-fluidic expert Mr. Lin Ping Cheng may refer to soon
Before the monograph " diagram Microfluid based Lab on a chip " that goes out, the monograph is published via Science Press, and the monograph is for micro-fluidic
Past of technology, now, and, in terms of vision of the future etc., suffer from detail, be deep into long discussion of detail.
So, the focal issue that this case that to have a talk below is paid special attention to.
The basic framework of micro-fluidic chip, including it is etched with the substrate of small fluid course and the cover plate fit together therewith,
Small fluid course on the substrate, assembling upper cover plate before, it is apparent on see to be exactly some micro-channels, wait until thereon
After covering cover plate, just real closure forms the small fluid course, and the conduit inner surface of the micro-channel is together with surround this
The part cover plate of micro-channel constitutes described small fluid course together；So, it is clear that this after assembling is completed is small
Fluid course, the major part of its inner surface area is the inner surface area of that micro-channel, in other words, in the micro-channel
The state or property on surface substantially determine the integrality or property of the small fluid course；Therefore say, this is built in base
The inner surface state or inner surface property of micro-channel on piece are key factors；In principle, it is any to keep or protecting substantially
The material of its solid forms is held, can be used to make substrate and cover plate, such as, the material that can act as substrate and cover plate can be with
It is monocrystalline silicon piece, quartz plate, sheet glass, high polymer such as dimethyl silicone polymer, polymethyl methacrylate, makrolon etc.
Deng；Certainly, the selection of substrate and the selection of cover plate be able to can also be differed with identical；From material consumption, manufacture difficulty and
From the point of view of in terms of application popularization prospect etc., between these materials exist not small difference, the especially selection of that substrate, influence compared with
Greatly.
In various substrate making materials, dimethyl silicone polymer, i.e. PDMS, comparatively very easily shaping, so
Substrate on make that micro-channel is extremely simple, and the lower cost for material makes substrate with the polydimethyl siloxane material,
Micro-channel is being suppressed or etched thereon, and is being engaged with the cover plate that the cheap material such as glass or polypropylene or other plastic sheets makes,
It is a kind of more satisfactory selection seemingly；Certainly, patch material can also select to use cheap polydimethyl siloxane material：
So, this substrate selection is the scheme of polydimethyl siloxane material, and material is extremely cheap, makes extremely simple, seems and should also be as
It is extremely easy to popularize, promotes.
But, thing is really not so simple.
First, this polydimethyl siloxane material, that is, the material that the letter PDMS that abridges is referred to, itself are a kind of strong
Hydrophobic material, micro-channel is built on this material, if without being operated for the modified of the micro-channel surface, then,
After overall assembling is completed, that is, cover after cover plate, because the micro-channel its inner surface in structure occupies most liquid circulation
The inner surface in road, then, its strong hydrophobic property of the PDMS micro-channels inner surface, is deciding factor, it can cause class
Be similar to the aqueous solution the fine liquid stream of polar liquid by becoming very difficult, its flow resistance is big, or even general Micropump is all
It is difficult to promote, certainly, if cover plate also selects to use the PDMS material, then, problem is substantially identical, similar；
Therefore, among prior art, modification is modified particular for the micro-channel inner surface on the PDMS material, is necessary
Operation；So, this is pretty troublesome for the modified operation of PDMS micro-channel inner surfacesThat falls nor this problem, structure
Perplex into serious technical, be another problem：PDMS polymer molecules tool inside its body phase of this PDMS material substrate
There are PDMS polymer molecules inside the characteristic for diffusing to the surface, migrating automatically, this substrate body phase to diffuse to the surface, move automatically
The characteristic of shifting, will cause the state after modification by its inner surface of that micro-channel of surface modifying and decorating can not maintain foot
Enough long time, the holding time for micro-channel its inner surface state after that is surface-modified is substantially only sufficient to complete in laboratory
The time of portion's test experiments needs；In other words, by surface modification or the PDMS micro-channel inner surfaces of surface modification, its
The surface state that is formed can not be lasting after modification or after saying modification, but soon automatically tend to or say and become surface again and change
Surface state before property, returns to the strong hydrophobic surface state of that script in the shorter time, then, just think,
Such micro-fluidic chip can largely make, mass storage, be widely popularized, and answer is it is obvious that is, impossible.
Micro-channel on this PDMS material, can not pump similar to the fine liquid stream of polar solvent of the aqueous solution if not doing surface modification
Send and pass through, chip also cannot just be used；And if having done surface modification, the state after its modification can not be persistently kept again, also
Being equally can not popularization and application.
So, how to accomplish that substrate can either be made using cheap PDMS material, and table in the micro-channel can be released
Face decorating state can not persistently, chip can not largely make, largely lay in so that be widely popularized it is such a make this area it is numerous specially
The puzzlement that industry personnel are entangled with for a long time, the highly difficult problem that exactly one its obvious technology barrier can not despise.
Be present many year in the highly difficult problem, so far, not yet properly settled.
Second, the PDMS material of non-surface modification, above it is stated that, its surface is strongly hydrophobic, this strong hydrophobic
Material surface and also another problem, that is, this strong hydrophobic PDMS surfaces can adsorb large biological molecule, and
And, these adsorbed large biological molecules can also further depression further on PDMS surfaces, gradually fall into gradually deep, directly
It is trapped in heavy within the body phase of PDMS substrates, in fact, this process is partly also due to inside PDMS material body phase
Polymer molecule, which has, to be diffused to the surface, caused by travel motion；Such case, can also be explained from another angle, i.e.
Continuously from inside PDMS body phases to its diffusion into the surface, migration those polymer molecules, its result moved, be by
Gradually those are involved within the body phase of PDMS substrates by the large biological molecule of adsorption, briefly, these are inhaled
Attached large biological molecule is exactly to be swallowed up by PDMS substrate body phases；So, this PDMS substrates body phase swallows up large biological molecule
Phenomenon, the influence caused by it necessarily causes the severe deviations of all kinds of test data of experiment for being related to large biological molecule.
As described above, be the problem of PDMS substrates, its not only adsorption large biological molecule, and swallow up large biological molecule,
So, as the large biological molecule of experiment test object, its disappearance will not stop because the absorption of surface saturation, but, no
It is disconnected adsorbed, also constantly swallowed up.
On PDMS substrates in related experiment test process its body phase constantly swallow up test associated biomolecule macromolecular phenomenon, separately
It is to say that one kind, which is explained, there are substantial amounts of Minute pores in PDMS body phases, and associated biomolecule macromolecular is by after adsorption, depression
Into these Minute pores, and then swallowed up；However, inventor thinks, those can allow the air point of miniature scale
Son squeezes into the Minute pores therebetween, and being not equal to them also can directly allow that the large biological molecule of relative large scale enters, and two
Person's difference on yardstick is huge, must not make sweeping generalizations.Explanation is bypassed, in any case, the biology of object is analyzed as dependence test
Macromolecular is adsorbed by PDMS substrate micro-channels inner surface, and then is constantly swallowed up by PDMS substrate body phases, and this is known objective
The phenomenon of presence.
, can be from containment PDMS surfaces to life in order to prevent this PDMS substrate bodies relative to the effect of swallowing up of large biological molecule
The absorption of thing macromolecular is addressed, and method is chemically modified modification aiming at the PDMS material surface, for
For PDMS is the situation of substrate material, modification exactly is chemically modified to the surface of described micro-channel part, by changing
The micro-channel inner surface of modification is learned, its absorption to large biological molecule can be contained, and then avoid large biological molecule quilt
PDMS substrate body phases are swallowed up；But, or that old problem, that is, the chemical modification on PDMS material surface changes
Surface state after property can not persistently be kept, the polymer molecule inside the PDMS substrate body phases its diffuse to the surface automatically,
The process of migration, soon can become that micro-channel inner surface state being modified by surface chemical modification again script strong and dredge
Water and the state of strong adsorption large biological molecule, in other words, no matter how professionals in the field turn from side to side, the PDMS
Its micro-channel inner surface of substrate is always rapidly to strong hydrophobic surface state evolution.
So, how can either obtain that PDMS material price is extremely cheap, substrate makes extremely easy benefit, can reach again
Growth stage contains absorption process of the PDMS substrate micro-channel inner surfaces to large biological molecule, and then prevents PDMS substrate body phases
The effect of swallowing up to large biological molecule so that related chip manufactured goods are able to maintain that a prolonged enough, rational shelf-life,
It is exactly a very intractable problem.The problem makes the numerous specialties in this area as another problem addressed above, equally
Personnel are entangled with, perplexed for a long time, and the problem is equally the highly difficult problem that its obvious technology barrier can not despise.The hardly possible
Also be present many year in topic, so far, also not yet properly settled.
Third, as described above, the PDMS micro-channel inner surfaces are strongly hydrophobic, and targetedly surface chemical modification or come to the surface
Learn modification to be difficult to again persistently, therefore, actually can only still belong to effective short in the surface state after the modification of its surface or surface modification
It is used within phase；If have passed through that ofer short duration period of validity, and still by force if use, due to surface shape
State already again close to hydrophobic state, is then certainly existed than larger flow resistance using usual Micropump driving test liquid stream,
So, just test liquid can only be forced to flow to target direction flowing by increasing Micropump pump power and pumping pressure, as described above,
This PDMS material is soft, pumps test liquid stream with too high, machinery pumping pressure, causing the substrate, it enters
Bubbling, expanded, distortion, deformation, also, this high-pressure situations occur for the micro-channel that sample end includes sample introduction end near zone
Under, also easily occur the stripping between substrate and cover plate, this feelings in the sample introduction end and its micro-channel of near zone and its periphery
Under shape, sample solution flows in the crack of the appearance between the substrate and cover plate that are formed after the entrance stripping everywhere, this reality
Border causes the damage of the micro-fluidic chip；Certainly, it is not in place if surface modification or surface modification script, also result in
There is said circumstances within the of short duration usual term of validity；It is above-mentioned in the case where carrying out liquid stream driving using additional Micropump merely
The problem exists all the time.If be modified or the pre action such as surface modification as described above, not doing any surface completely,
So, the above-mentioned problem will be even more serious, even without occur micro-channel bubbling described in sample introduction end and its near zone, it is expanded,
Between distortion, deformation and substrate and cover plate the problems such as peel off, merely because the flow resistance is excessive, using high pressure Micropump also not
Test liquid stream must can be driven to be marched forward towards terminal side.
