Summary: Redox-active MIP-Gly NPs were developed by incorporating ferrocenylmethyl methacrylate into the synthesis process, enabling them to selectively determine glyphosate without the need for redox probe. MIP-Gly NPs synthesized using allylamine and squaramide-based monomers exhibited the highest selectivity. The MIP-Gly NPs modified Pt-SPEs were characterized using differential pulse voltammetry and electrochemical impedance spectroscopy, with changes in the oxidation peak of the ferrocenyl moieties serving as the analytical signal. The chemosensor showed a low limit of detection and a wide linear dynamic concentration range for glyphosate, allowing successful detection in spiked river water samples.

Summary: In order to ensure environmental and industrial sustainability, the extraction of cadmium ions (Cd(II)) from effluents is necessary. However, achieving high-efficiency Cd(II) extraction has been challenging due to slow rates and low selectivity. This study utilized an ion-imprinting method to imprint Cd(II) onto a thiosemicarbazide-chitosan derivative (TCCS), which was synthesized through an unconventional synthetic route. The developed Cd-TCCS exhibited significantly higher adsorption capabilities and enhanced adsorption selectivity when compared to non-imprinted sorbent.
