Applications of biosensors for bacteria and virus detection in food and water-A systematic review

Biosensors for sensitive and specific detection of foodbome and waterborne pathogens are particularly valued for their portability, usability, relatively low cost, and real-time or near real-time response. Their application is widespread in several domains, including environmental monitoring. The main limitation of currently developed biosensors is a lack of sensitivity and specificity in complex matrices. Due to increased interest in biosensor development, we conducted a systematic review, complying with the PRISMA guidelines, covering the period from January 2010 to December 2019. The review is focused on biosensor applications in the identification of foodbome and waterborne microorganisms based on research articles identified in the Pubmed, ScienceDirect, and Scopus search engines. Efforts are still in progress to overcome detection limitations and to provide a rapid detection system which will safeguard water and food quality. The use of biosensors is an essential tool with applicability in the evaluation and monitoring of the environment and food, with great impact in public health.

Automated summary

Biosensors are valuable for detecting foodborne and waterborne pathogens due to their portability, usability, and real-time response. However, current biosensors lack sensitivity and specificity in complex matrices. A systematic review of biosensor applications in identifying microorganisms was conducted, revealing ongoing efforts to overcome detection limitations and safeguard water and food quality. Biosensors are essential tools for evaluating and monitoring the environment and food, with significant impact on public health.
