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: An intricate mesh structure of manganese oxide nanowires and carbon nanotubes was synthesized and strengthened by a molecularly imprinted network to generate template cavities and impart selective recognition. This mesh structure, termed as MIP@MnO:CNT, was used as the receptor interface for microarray transducers to detect para-nitrophenol, a pollutant, with exceptional sensitivity and selectivity compared to other aromatic compounds. Moreover, this designed interface was able to detect para-nitrophenol in water samples.

Summary: In this study, a dual-recognition sensor (MF-MIPs) was developed for highly selective and sensitive detection of 4-nitrophenol in food samples using surface imprinting, magnetic separation, and fluorescent detection. The sensor showed good linear response, low detection limit, high anti-interference capability, excellent stability, and reusability. This method may be a promising approach for 4-NP detection in food samples.

Summary: This study synthesized a composite of reduced graphene oxide (rGO) and zinc oxide nanorods (ZnO) called rGO@ZnO, and tested its photocatalytic performance for reducing para-nitro phenol (PNP) to para-amino phenol (PAP) under both UV and visible light irradiation. The sample rGO(5)@ZnO exhibited remarkable photocatalytic activity, achieving a PNP reduction efficiency of approximately 98% within four minutes.

Summary: A proof-of-concept sensor based on a molecularly imprinted polymer (MIP) synthesized with a THC template has been developed for the sensitive and selective detection of THC. Raman spectroscopy was used to analyze the THC template and perform label-free monitoring of THC based on a single identifying Raman peak. The MIP sensor showed a high sensitivity and selectivity for THC detection, with a low detection limit and specific recognition sites for THC in the synthesized MIP sensing material.
