METHOD FOR DETECTING FOOD-NOXIOUS SUBSTANCE

WIPO Patent Application WO/2023/033582

A1

The present invention relates to a method for detecting a food-noxious substance and, more specifically, to a method for detecting a food-noxious substance wherein, with selective molecular affinity, a food-noxious substance-specific aptamer is bound to a capture probe fixed to a chip in the absence of the food-noxious substance, but departs from the capture probe and binds to the food noxious substance in the presence of the food-noxious substance, so that a circular DNA binds to the capture probe and undergoes an RCA reaction to form a metal body for signal amplification, whereby detection accuracy can be improved.
