Fast detection of isocarbophos using bis-propargylcalix[4]arene-stabilized silver nanoparticles.

Bis-propargylcalix[4]arene-stabilized silver nanoparticles (BPCA-Ag NPs), as a chemosensor for detecting an isocarbophos (ICP) pesticide in an aqueous medium, are reported in this work. The nanoparticles were characterized by UV-visible spectroscopy, dynamic light scattering, zeta potential and high-resolution transmission electron microscopy techniques. It was observed that the BPCA-Ag NPs had a high selectivity for isocarbophos with a detection limit of 1.
