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

open access: yesFood 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
