▎ 摘　　要

(CN212845415-U) NOVELTY - The utility model claims a micro-flow control chip for tumour marker detection, the chip comprises a reaction layer substrate and a micro-flow channel sample layer on it; the reaction layer substrate comprises a glass slide substrate and graphene oxide quantum dot nano material substrate assembled on the glass slide substrate; the graphene oxide quantum dot nanometre material substrate is printed with a strip-shaped detecting belt and a quality control belt; the bottom of the micro-channel sampling layer is provided with a plurality of micro-channel groove; a plurality of the micro-channel groove and a plurality of the strip-shaped detecting belt and a quality control belt are vertically arranged to form a plurality of reaction lattice; the micro-channel sampling layer is further provided with an inlet hole and an outlet hole through up and down; two ends of the micro-flow channel groove are respectively connected with the inflow hole and outflow hole. The chip claimed by the utility model can detect multiple different tumour markers at the same time; it is fast and stable; it can detect the field high flux. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for: a method for tumor marker detection using the microfluidic chip. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the overall structure of the microfluidic chip for detecting tumor marker.
