At least mixture formation or hybridization between 2 basic molecules the method of detection which is detected on the basis of the expansion signal in the said backing on the solid backing

摘要

A method for detecting at a solid support (3) complexing or hybridization between at least two basic molecules (8 and 9), one of the molecules being initially fixed on support (3), called identifying molecule (8), and the other being in solution in liquid sample (2), called target molecule (9). A solid support for detecting complexing or hybridization between at least two different molecules, a biochip incorporating the support and use of the biochip in a diagnostic test are also disclosed. The method includes: using chemical or biological element (10), specifically bound to the formed complex or hybrid; exciting the complex or the hybrid, so that chemical or biological element (10) releases light signal (11); receiving and transforming light signal (11) into chemical signal (15) at support (3), and detecting electric signal (12) derived from chemical signal (15).
