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 analysed 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.

A microstructured chip (3;
- 33;
- 43;
- 53;
- 63) for surface plasmon resonance (SPR) analysis which is in the form of a solid consisting of a base (5;
- 77), of an upper face (4;
- 44), at least one part of which is covered with a metal layer (2;
- 22;
- 42;
- 52;
- 62), and of at least one side face (55;
- 66), wherein:
- said upper face (4;
- 44) is provided with at least two zones of micrometric size intended to receive species to be analyzed, chosen from at least one cavity and/or at least one protuberance (1;
- 11;
- 41;
- 51;
- 61);
- said zones being separated from one another by planar surfaces;
- and
- at least one of said zones is different from the others.
