This study presents the development of a high-performance electrochemical sensor predicated on a dual-functional monomer molecularly imprinted polymer (MIP) specific recognition mechanism, designed for the highly sensitive and selective detection of caffeine in beverages. Innovatively, the sensor utilizes electroch...
We have developed a novel electrochemical-colorimetric dual-modal sensor based on a metallosalen-based covalent organic framework (Salen-COF) for separate electrochemical quantification of uric acid (UA) and dopamine (DA) and colorimetric screening of their total amount. The Salen-COF was synthesized via a Schiff-base...
Dinotefuran (DNF), a third-generation neonicotinoid insecticide, requires sensitive and reliable residue monitoring in agricultural products. Here, a ternary β-cyclodextrin/carboxylated multi-walled carbon nanotube/graphene oxide (β-CD/MWCNTs-COOH/GO) nanocomposite was developed as a voltammetric sensing interface for...
An exceptional electrochemical sensing platform was engineered by integration of cobalt-gadolinium mixed metal oxides (CGOs) with an amine functionalized lanthanum metal organic framework (NLF) to yield a hierarchically porous NLF@CGO hybrid. The carbon nanosphere (CNS) template provides the CGO nanoparticles with abun...
Aloe emodin (AE, 1,8-dihydroxy-3-(hydroxymethyl)anthraquinone) is a naturally occurring anthraquinone derivative with well-documented anticancer, antiviral, and anti-inflammatory properties, making it an important target for sensitive analytical determination. In this study, a novel electrochemical sensor based on a di...
Perfluorooctanesulfonate (PFOS) is a highly persistent and toxic per- and polyfluoroalkyl substance (PFAS) widely recognized for its serious risks to both environmental and human health. In this work, an electrochemical impedance spectroscopy (EIS)-based sensor was developed for PFOS detection by integrating a MIL-101(...
