A method of positioning an organic, biological and/or medical specimen in a desired surface region of a specimen carrier, whereby a magnet device is provided, including joining the specimen with one or a plurality of magnetic, in particular paramagnetic particles, arrangement of the magnet device relative to the specimen carrier so that a desired magnetic field arrangement is provided in a predetermined region of the specimen carrier, introduction of the specimen into the specimen carrier and arrangement of the specimen in the desired surface region with the aid of the magnet device.


The invention relates to a method of positioning an organic, biological and/or medical specimen in a desired partial region of a specimen carrier, comprising the steps arrangement of a gel in a partial region of the specimen carrier, polymerisation or gelification of the gel, by means of which a polymerised gel is obtained, whereby the polymerised gel at least partially, in particular horizontally, delimits the desired partial region and introduction of the specimen into the specimen carrier, in particular into the desired partial region of the specimen carrier.

The invention relates to polymer substrates which are provided with fluorescence features and in which photochemical fluorescence features, i.e. fluorescent structures, are produced by UV irradiation. Thus, fluorophores can be produced in polymer substrates with a low inherent fluorescence by means of suitable UV radiation, which fluorophores display a marked and detectable emission upon being excited with light of a suitable wavelength. If such an irradiation is implemented in a structured manner, emission patterns can be produced in this way in polymer substrates, which emission patterns can be applied for example as recovery grids in fluorescence microscopy. A further application field relates to product authentication which is made possible by the polymer substrates according to the invention provided with fluorescence features.


A microfluid device for producing diffusively built gradients comprising a bottom plate and a cover plate, wherein the cover plate has recesses and is connected to the bottom plate in a liquid-tight manner so that the recesses form at least two reservoirs and one observation chamber, which connects the reservoir, a reservoir can be filled particularly through an inlet/outlet through the cover plate, and the cross-sectional surface of the observation chamber is at least 5 times, preferably at least 200 times smaller at the aperture of the observation chamber into one of the reservoirs than the maximum cross-sectional surface of the reservoir in parallel to this cross-sectional surface of the observation chamber.
