Detecting a complex or hybrid formed by at least two molecules, on a solid carrier surface of a biochip, where one molecule is attached to the surface as a search molecule and the other is in a sample solution as the target molecule, is new. Detecting a complex or hybrid formed by at least two molecules, on a solid carrier surface (3) of a biochip, where one molecule is attached to the surface as a search molecule (8) and the other is in a sample solution as the target molecule (9). A chemical or biological agent (10) is used, specifically linked to the developed complex or hybrid. The complex/hybrid is excited, so that the agent emits a fluorescent signal (11). The luminescence is detected and converted into a chemical signal (15) at the biochip level, to be registered (6) as an electrical signal (12) for analysis. The chemical signal is generated by a metal precipitation, preferably of silver halide.
