Nucleic-acid biosensors have emerged as useful tools for on-farm detection of foodborne pathogens on fresh produce. Such tools are specifically designed to be user-friendly so that a producer can operate them with minimal training and in a few simple steps. However, one challenge in the deployment of these biosensors is delivering precise sample volumes to the biosensor's reaction sites.

- Laboratory-based nucleic acid amplification tests (NAATs) are highly sensitive but slow, requiring sample transport, while recent advancements have led to affordable and rapid paper-based point-of-care (POC) NAATs during the COVID-19 pandemic.
- A new portable paper-based testing platform called LAMP has been developed for on-farm use, which can quickly detect fecal contamination by analyzing samples in under an hour with high accuracy (100% concordance with lab tests).
- This innovative LAMP testing platform aims to enhance decision-making in the fresh produce industry and encourages further development of on-farm diagnostics to ensure better food safety and advance agricultural technology.
Article Synopsis
- Paper-based biosensors are cost-effective and portable devices designed for the easy detection of biochemical substances, especially useful for point-of-care testing.
- Nucleic acid-based methods provide flexibility in detecting pathogens, and when combined with paper-based platforms, they enable accurate results in a non-laboratory setting.
- The review covers current technologies, examines challenges in integrating these systems, and suggests future research avenues to enhance paper-based biosensor development.
