Definitions
- the invention relates to a micro- and nanofluid system for the dynamic structural analysis of linear macromolecules with energetically preferred folding structure in an acted upon with an electric field and / or a delivery pressure fluid channel with at least one entropic barrier for deployment of the flowing macromolecules and an irradiation channel for electromagnetic radiation.
- Micro- and nanofluidic systems are, in analogy to microelectronic systems, on glass or plastic substrates or highly integrated also on microchip manufactured silicon chips arranged systems of finest channels, caverns, inflows and outlets and optionally with microactuators such as pumps, Valves and so on.
- the literature describes systems with structures of a few microns down to the nanometer scale.
- Such systems also with integrated sensors, such.
- miniaturized analyzer systems, spectroscopic flowmeters, or miniaturized bioreactors are being used in many novel applications and measurements in modern biology, biotechnology, chemistry, and biochemistry pharmaceutical, analytical and clinical chemistry, environmental analysis, process control, food chemistry and monitoring.
- Macromolecules can then be separated and detected in nanoscale structures.
- radiation is often transmitted with light defined wavelength and optical detectors for recording the light of the transmission response or after marking corresponding areas on the macromolecule and fluorescence detection methods used.
- Under light for detection is not necessarily visible or this closely adjacent light to understand, but in principle any electromagnetic radiation that can be focused by specific, in the literature always called optics facilities and judge.
- an energy adapted to the size of the radius of gyration must be applied for the unfolding or at least for the significant flattening of the macromolecule in the form of a delivery pressure in the fluidic system and / or an electric field. If the delivery pressure is initially chosen so high that all but the largest macromolecules can leave the first extension region and subsequently reduced in the temporal progression of the migration rate of the macromolecules, the macromolecules will collect separately according to their gyration radii in the various extension regions Sorted way.
- a delivery pressure in the fluidic system and / or an electric field If the delivery pressure is initially chosen so high that all but the largest macromolecules can leave the first extension region and subsequently reduced in the temporal progression of the migration rate of the macromolecules, the macromolecules will collect separately according to their gyration radii in the various extension regions Sorted way.
- FIG. 7 and 12C show an arrangement of nanopillars as an entropic barrier and their use for the unfolding of macromolecules (FIG. 7). Again, a corresponding delivery pressure must be applied, but a simple flattening of the macromolecules due to the passage cross-sections caused by the columns is out of the question, but it must take place to a large extent to complete unfolding.
- US 2004/0197843 A1 describes an array of nanochannels which can take up unfolded macromolecules for structural analysis in an integrated system (see FIG. 5).
- the channels may have a cross section between one and one hundred square nanometers and lengths up to 10 cm. In channels of this length, a complete stretched chromosome of the human genome with approximately 250 million base pairs is to be recorded.
- the macromolecules to be unfolded are stored in a reservoir located in front of the nanochannels, and e.g. transported by electric fields into the nanochannels.
- An entropic barrier that promotes deconvolution and prevents clogging of the nanochannels is not provided for in the description.
- the structure analysis can be carried out by means of light, by a current or resistance measurement or by measuring the change of charge states.
- the detection will be described by means of a focused laser beam.
- the macromolecule to be analyzed is passed through the entropic barrier in which it unfolds increasingly, until it finally enters fully stretched in the diameter adapted nanochannel and there is full length space. Subsequently, it is illuminated with the laser beam and processed by him due to its structure changed light in a detector, here a camera equipped with a CCD chip. Deconvolution and detection thus take place at two neighboring sites, the entropic barrier and the nanochannels.
- the described detection system with focused laser beam and CCD camera or alternatively other recording device can make the mentioned in the publication potential possibility of achievable due to the full extension of the macromolecule appearing resolution of individual base pairs.
- photonic crystals are known, which are described as three-dimensional dielectric structures which are impermeable to electromagnetic radiation in a certain wavelength range, regardless of the direction of incidence.
- the corresponding wavelength range is determined essentially by the arrangement, shape and size ratios of the structure.
- An important form of photonic crystals is formed by a regular matrix-like arrangement of microcolumns or cylinders. Due to the properties described here, photonic crystals are suitable for producing optical components such as narrowband filters, modulatable filters, add-drop filters or integrated optical structures with 90 ° deflection, eg for optical data transmission in optical waveguides with different wavelengths of light DWMD technology (Dense Wavelength Division Multiplexing).
- DWMD technology Dens Wavelength Division Multiplexing
- EP 1 729 111 A1 describes a system for analysis, in particular density determination, for a non-descript analyte (target substance) with a source of electromagnetic radiation, a photonic crystal as sensor element and a detector, source and detector being connected to the photonic waveguide structures Crystal are connected.
- This has a two-dimensional arrangement of circular openings (pores) with a diameter of 240 nm with a mesh size of 420 nm and non-porous zones, so-called Resonatorblazen on.
- the analyte is directed through the circular openings perpendicular to the plane of the two-dimensional photonic crystal, thereby changing its transmission properties for the electromagnetic radiation.
- the application of this and the decrease of the transmitted radiation takes place in the plane of the photonic crystal. Unfolding and analysis of linear macromolecules is not possible with this arrangement.
- FIG. 2004/001465 A1 Another photonic crystal is proposed in WO 2004/001465 A1.
- a number of microchannels also extending over the entire length of the photonic waveguide section are arranged around a central channel. Their arrangement, diameter and cross-sectional shape can be chosen as desired for the parameterization of the properties.
- the microchannels are filled with air or evacuated, the analyte flows through the central channel.
- the central channel of a suitably selected stretched photonic waveguide section is traversed and also lengthwise of a End applied with electromagnetic radiation. The transmission result is tapped at the other end and fed to a detector.
- the object of the present invention is therefore to be seen, starting from the generic prior art, to describe a micro and nano-fluid system in which further integration of the elements for the development of the macromolecules and structural analysis are combined in a common element and the Resolution down to the single building block of linear macromolecules, eg a single base pair, can be increased.

- the photonic crystal Transverse to the fluid channel, the photonic crystal forms the irradiation channel for irradiating the deployed linear macromolecules.

- micro- and nano-fluid system is characterized by an expansion of the lattice openings of the periodic lattice structure of the photonic crystal between 5 nm and 1000 nm.
- the diameter of unfolded linear macromolecules can vary depending on the type.

These and thus the extent of the grid openings can be adapted during manufacture to the intended task.
- Lattice structure of the photonic crystal as a nanoscale field The prior art describes a microcolumn field preceded by nanochannels, which in turn serve to accommodate the deployed linear macromolecules. This two-part arrangement can be dispensed with since the linear macromolecule does not first have to be unfolded in its entirety in order to analyze it. It may as well be in a priori as Nanoparticle designed photonic crystal as an entropic barrier unfolded at least in sections and analyzed simultaneously.

- Properties of a photonic crystal make it possible to guide, guide or concentrate electromagnetic radiation to dimensions below its wavelength. This is achieved by incorporating defects into the periodic structure of the photonic crystals. A defect is any disturbance of the otherwise regular crystal structure.
- Defects are single or combinations of contiguous or non-contiguous chains of structures arranged one behind the other or individual structures that differ from the remaining structures in the lattice structure by their geometry. This also includes single or combinations of related or non-consecutive missing structures in the photonic crystal. By incorporating such defects into the photonic crystal, the electromagnetic radiation can be selectively guided.
