QCM Biosensors for pathogen detection in water and food: review of published literature

Introduction:This article is the result of the review “QCM Biosensors for the Detection of Pathogens in Water and Food: A Review,’ conducted during the years 2023 and 2024 at the Universidad Distrital Francisco José de Caldas”Problem: The fast evolution of pathogen detection through biosensors requires a continuous synthesis of literatu-re to provide an integral comprehension of the state of the art to new researchers. Objective:Perform bibliography research about QCM Biosensors used for pathogen detection in food and water covering a period from 2018 to 2023.Methodology: The research includes three phases: An explanation of the principles of QCM biosensors, their use in water and food pathogen detection, and their use in industry, with an emphasis on water quality.Result:QCM biosensors are solid, measure mass changes at the micro and nanometric scales, and are widely used in the food industry due to their accuracy and ease of use.Conclusion: The review highlights the effectiveness of QCM biosensors when detecting different food contami-nants and pathogens. It underlines the practical research necessity and importance of updating review papers to orientate future investigations in this specific area.Originality:The originality of this review lies on its detailed approach to QCM biosensor use in food pathogen detection.Limitations:The constant evolution of the field of pathogen detection in addition to the diversity of QCM biosen-sors and the wide range of pathogens studied may make it difficult to generalize certain findings.
