Cyclen dithiocarbamate-functionalized silver nanoparticles as a probe for colorimetric sensing of thiram and paraquat pesticides via host–guest chemistry
Abstract: We have developed a simple and rapid colorimetric method for on-site analysis of thiram and paraquat using cyclen dithiocarbamate-functionalized silver nanoparticles (CN-DTC-Ag NPs) as a colorimetric probe The synthesized CN-DTC-Ag NPs were characterized by UV–Visible spectroscopy (UV–Vis), Fourier transform infrared spectroscopy, dynamic light scattering, and transmission electron microscopic techniques The CN-DTC molecules provide good supramolecular self assembly on the surfaces of Ag NPs to encapsulate thiram and paraquat selectively via “host–guest” chemistry, resulting in red-shift in surface plasmon resonance peak of CN-DTC-Ag NPs from 396 to 530 nm and 510 nm and color change from yellow to pink for thiram and to orange for paraquat, which can be naked-eye detected The present method shows good linearity in the range of 100–200 µM and of 500–250 µM with limits of detection 281 × 10−6 M and 721 × 10−6 M for thiram and paraquat, respectively This method was proved as a promising tool for on-site and real-time monitoring of thiram and paraquat in environmental water, potato, and wheat samples
