摘要

micro structured chip, spr analysis device, spr measurement process and use of the device the present invention refers to a micro structured chip (3; 33; 43; 53; 63) for resonance analysis of surface plasmons (spr ) in the form of a solid consisting of a base (5; 77), an upper face (4; 44) in which at least part is covered by a layer of metal (2; 22; 42; 52; 62), and at least one side face, (55; 66), characterized by: said upper face being provided with zones of micrometric size intended to receive species for analysis chosen from n protrusions in cavities; and when n + m greater than 2, said zones are separated from each other by flat surfaces, with n ranging from 1 to j, m ranging from 0 to i; j and i being integers.
