Abstract
Disclosed are a detection chip and a modification method therefor. The method for modifying the detection chip comprises performing a surface film-forming treatment on a hydrophilic layer on a first substrate constituting the detection chip to form polydopamine film on a surface of the hydrophilic layer; and adopting a buffer solution containing sodium hyaluronate to perform a surface carboxylation treatment on the hydrophilic layer, on the surface of which the polydopamine film has been formed, in order to form a carboxyl-containing modification group on the surface of the hydrophilic layer.
