Abstract
A microstructured chip (3; 33; 43; 53; 63) for surface plasmon resonance (SPR) analysis, taking the form of a solid formed by: a base (5; 77); an upper surface (4; 44), at least part of which is covered with a metal layer (2; 22; 42; 52; 62); and at least one side surface (55; 66). The chip is characterized in that the aforementioned upper surface is provided with micrometric zones intended to receive species to be analyzed and selected from among n protrusions and m cavities, and in that when n+m≧2 the zones are separated from one another by planar surfaces, with n varying between 1 and j, m varying between 0 and i, and j and i being integers.
