Summary
This narrative review examines electrochemical biosensor technologies for on-site food safety analysis, covering detection of biological and chemical contaminants and genetically modified organisms. The authors synthesise recent advances in electrode materials, modification strategies, and electrochemical methods, highlighting the advantages of these platforms for rapid, sensitive, and selective detection using minimal sample. The review concludes that electrochemical biosensors offer promising miniaturised platforms for food safety monitoring, though it does not synthesise comparative efficacy data or make recommendations for specific applications.
Regional applicability
The review is methodologically global in scope, addressing electrochemical biosensor technology platforms applicable across jurisdictions. Findings on miniaturisation and on-site detection capability may be particularly relevant to United Kingdom food safety regulation and enforcement, though the review does not explicitly address UK policy contexts or supply chains.
Key measures
Detection limits, sensitivity, selectivity, response time, miniaturisation, cost, sample volume requirements
Outcomes reported
The review synthesises the latest electrochemical biosensor technologies for detecting biological contaminants, chemical contaminants, and genetically modified crops in food products. It evaluates these platforms based on analytes of interest, electrode materials and modification methods, electrochemical methods, and detection limits.
