Fine structure chip for surface plasmon resonance analysis, analysis apparatus including the fine structure chip, and use of the apparatus

摘要

The present invention relates to a microstructure chip for surface plasmon resonance (SPR) analysis, which takes the form of a solid formed by a bottom surface, a top surface at least partially coated with a metal layer, and at least one side surface. . The chip has at least two micrometer-level regions intended to receive the species to be analyzed on the upper surface (4, 44), at least one cavity and / or at least one protrusion (1, 11). , 41, 51, 61), the regions are separated from each other by a plane, and at least one of the regions is different from the others.
