Opposite changing dual-emission luminescence of gold nanoparticles by sulfhydryl to develop a pesticide biosensing strategy

Abstract

Opposite changing dual-emission luminescence of gold nanoparticles by sulfhydryl-containing compounds was found for the development of a pesticide biosensing strategy.

A Highly Sensitive Electrochemical Sensor Based on Electrocatalytic Reduction Effect of Cu2+ on Trace Determination of Malathion in Soil and Other Complex Matrices

“…Numerous techniques, such as Fourier transform (FT) infrared [17,18], FT-Raman spectrometry [19], GC-MS [20][21][22][23], cloud point extraction (CPE) [24], fluorescence [7,10], spectrophotometry [25,26], dispersive liquid-liquid microextraction combined UV spectrophotometry [27], indirect atomic absorption spectrometry [28], opposite changing dual-emission luminescence of gold nanoparticles by sulfhydryl [6], carbon dots [7], and screen-printed enzyme electrodes [29], have been reported for trace determination of malathion in complex matrices. Despite the reliability of the protocols mentioned above, some complexities and drawbacks (e.g., use of toxic constituents and solvents, high cost, and expensive instrumentation linked with operational complications) have been associated with most of these techniques [17][18][19][20][21][22][23].…”
