Abstract
In this study, a highly sensitive fluorescent probe based on bovine serum protein-protected gold nanoclusters (BSA-AuNCs) was developed for the determination of organophosphorus pesticides (OPs).
Highlights
In the past decade, metallic nanoparticles have been used as probes to detect organophosphorus pesticides (OPs) because they exhibit unique physical and chemical properties.[30]
Compared with semiconductor quantum dots (QDs) and organic dyes, NCs are ultrasmall and nontoxic and show high uorescence and good biocompatibility; this means that they can be used for biological testing such as in biological imaging, speci c protein detection, and biosensing
These results indicated that bovine serum albumin (BSA)-encapsulated AuNCs with bright uorescence were successfully obtained using BSA as a precursor
Summary
Metallic nanoparticles have been used as probes to detect OPs because they exhibit unique physical and chemical properties.[30]. For the optimal test condition for the detection of OPs by the BSA-AuNC/AChE uorescent probe, we optimized the concentrations of AChE and ATCI to make the uorescence of BSAAuNCs almost quenched.
