Pesticide residues resulting from high dosage of pesticides in agricultural production are increasingly threatening human life and health.In that case,researchers are devoted to developing simple new techniques for the quantitative detection of pesticide residues.Carbon quantum dots are a new type of fluorescent carbon nanoparticles with excellent optical properties and biocompatibility,which are easy to realize surface functionalization.Therefore,fluorescent probes based on carbon quantum dots have a good application potential in detection of pesticide residues.In this paper,the research on carbon quantum dot based fluorescent probes is reviewed,the characteristics and synthesis of carbon quantum dots are briefly presented,the latest application progress of carbon quantum dots as fluorescent probes in pesticide residues detection is detailedly introduced,and the problems that have yet to be resolved are summarized.Finally,the future development direction is also forecasted.
