Synthesis and application of new silver and sulfur decorated S-doped reduced graphene oxide in ultra-trace analysis of pesticides by ion mobility spectrometry

Abstract

In this research, a novel, facile, and affordable method was presented for the synthesis of Ag/S/S-RGO nanocomposite. The resulting new nanocomposite was identified by FT-IR, XRD, FESEM, and EDX and...

A new colorimetric aptasensor for paraquat detection based on the designed aptamer with multiple paraquat binding sites in combination with gold nanoparticles

“…Several approaches have been established to quantify paraquat residues, including liquid chromatography, 6 high performance liquid chromatography, 7 fluorescence assay, 8 ion mobility spectrometry, 9 surface-enhanced Raman spectroscopy, 10 electrochemistry, 11 and electrochemiluminescence-fluorescence sensing. 12 Although these methods demonstrate high sensitivity in detecting paraquat, they are accompanied by certain limitations such as high costs, the prerequisite of advanced laboratory instruments, intricate procedures, time-consuming processes, and the requirement for skilled technicians to operate them.…”
