Recent Paradigms in Nanomaterial‐Assisted Electrochemical (Bio) Sensing for Food Quality and Safety Analysis: A Critical Review

Food Safety and Health, EarlyView.
ABSTRACT Rising global demand for safe and unadulterated foods has accelerated the need for rapid, low‐cost, and portable analytical technologies. Traditional laboratory methods, although accurate, are often labor‐intensive and unsuitable for decentralized, real‐time monitoring. In response, nanomaterial‐assisted electrochemical sensors have emerged as

Chlorfenapyr Induces Hepatotoxicity Associated With Oxidative Stress and Mitochondrial Dysfunction Involving Keap1/Nrf2 Signaling

Journal of Applied Toxicology, EarlyView.
ABSTRACT Chlorfenapyr (CHL) is a widely used pyrrole insecticide, but its hepatotoxic effects and underlying mechanisms remain incompletely understood. This study investigated the toxic effects of CHL on rat liver and BRL‐3A hepatocytes and explored the involvement of the Keap1/Nrf2 signaling pathway. Rats were administered CHL (10, 20, or 30 mg/kg) by

Sustainable and miniaturized electrochemical sensors for glyphosate and parabens: integrating biomass‐derived carbons, FDM fabrication, and portable instrumentation

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract Glyphosate and parabens are chemically distinct emerging contaminants whose field monitoring is constrained by complex matrices and by the cost and infrastructure requirements of conventional laboratory methods. This review evaluates whether biomass‐derived carbon materials, fused deposition modeling (FDM), and portable electrochemical ...
