Abstract: The invention is related to the field of biotechnology, specifically to the investigation of biomolecular interactions and sensing of biomolecules using a surface plasmon resonance. The biological sensor and a method of its production based on the thin films of graphene, graphene oxide, or single-walled or multi-walled carbon nanotubes are described. The technical results of the invention are a high sensitivity of the biosensor in combination with a high biospecificity; an expansion of the range of device applications; the protection of the metal film from an environmental exposure; the possibility to detect large biological objects.

Abstract: The micropump includes continuous cylindrical separating pipes having at least two alternating stages of pipes of small radius and large radius connected in succession. Each pipe of a large radius has one end as a hot zone, and the opposite end as a cold zone. The pipes alternate straight pipes with a large radius and U-shaped curved pipes with a small radius. The relationship of the large radius (R) to the small radius (r) is in a range of R/r=2 to 10000, while the relationship of the temperature (T2) of a hot zone to the temperature (T1) of a cold zone is T2/T1=1.1 to 3.0. The length and radius measurements of a straight pipe and a U-shaped pipe ensure a given change in temperature of the gas from the temperature of the hot zone to the temperature of the cold zone.
