Biochip, useful for detecting nucleic acid or protein, has its binding sites arranged as a ring on the functional surface to ensure homogeneous detection of light emission from labeled probes from all positions

摘要

A biochip (1) comprising a support (2) the active side (2a) of which comprises a functional surface (3) with an array of elementary sites (Xn) and many ligands, with many copies of each ligand fixed to different Xn, is new. The new feature is that (2a) comprises at least one ring (31) of Xn and a non-functional surface (4), positioned inside, or at the center of (31). An Independent claim is also included for a device, e.g. a disposable device, for determining at least one target species that comprises (1).
