Abstract: The invention relates to a microfluidic system comprising: a) a solid support comprising at least a first group of oligonucleotides, i. wherein each oligonucleotide in said group comprises a nucleic acid sequence of a first type, of a second type and/or a further type, ii. wherein said nucleic acid sequence of a first type is a barcode sequence, iii. and oligonucleotides comprising the same barcode sequence are grouped together in a group of oligonucleotides on said solid support, iv. wherein the first and further oligonucleotide groups are spatially separated on said solid support, b) wherein said one or more groups of oligonucleotide groups on said solid support are within separate reservoirs of the microfluidics system, c) wherein the one or more reservoirs are accessible to fluids, cells, chemicals and/or microdroplet by means of channels, and d) wherein each reservoir comprises comprising a group of oligonucleotides on said solid support is also trap for a microfluidic droplet.

Abstract: Provided herein are methods for identifying cognate pairs of a ligand species and a receptor species. The methods comprise (a) providing a set of ligand species, wherein each ligand species is represented at least one time; (b) providing a set of receptor species, wherein each receptor species is represented at least one time; (c) contacting the set of ligand species with the set of receptor species in a microreactor, wherein upon selective binding of a ligand species with a receptor species an enhanced signal is produced; (d) detecting a cognate pair of ligand species and receptor species by the production of the enhanced signal; and (a) identifying the cognate pair of ligand species and receptor species.

Abstract: A system (100) and a method for detecting fluorescence is disclosed. The system (100) essentially comprises a labelled sample wherein said labelled sample emits an electromagnetic radiation of a defined wavelength when irradiated by a LASER beam of a commensurate wavelength, a source (102) for emitting said LASER beam, oriented as to aim at said labelled sample, a chamber for holding said labelled sample during said LASER irradiation, a reflective layer (108) positioned to reflect said electromagnetic radiation, and a detector (112) positioned to detect and amplify said electromagnetic radiation.
