MICROSTRUCTURED CHIP COMPRISING CONVEX SURFACES FOR SURFACE PLASMON RESONANCE ANALYSIS ANALYSIS DEVICE CONTAINING SAID MICROSTRUCTURED CHIP AND USE OF SAID DEVICE

摘要

The present invention is a cube formed by a base surface (5; 77), a top surface (4; 44) at least partially covered with a metal layer (2; 22; 42; 52; 62), and at least one side (55; 66). Microstructured chips (3; 33; 43; 53; 63) for surface plasmon resonance (SPR) analysis, taking the form of The chip has micrometer-sized zones whose top surface is selected from n protrusions and m cavities and intended to accommodate the species to be analyzed; When n + m ≥ 2 (n is 1 to j, m is 0 to i, j and i are integers), the zones are characterized by being separated from each other by flat surfaces.
