Construction of a three-mode sensor based on gold nanoparticles and carbon quantum dots as probes for the detection of thiosemicarbazone

Abstract

A three-mode sensor for thiocarbazone (TSC) was constructed based on gold nanoparticles and carbon quantum dots (CQDs). (A) Synthesis process of CQDs using ginkgo leaves. (B) Colorimetric and chrominance TSC detection. (C) Fluorescence detection of TSC.
