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 1.0 x 10(-6) M. According to the result of this research, the BPCA-Ag NPs were found to be useful for the colorimetric detection of isocarbophos in an aqueous medium. It provides a new method for in situ detection of isocarbophos using host-guest interaction.
