ClearBiosensors in environmental analysis of microplastics and heavy metal compounds – A review on current status and challenges
This review examines how biosensors -- devices that use biological materials to detect pollutants -- could provide faster and cheaper monitoring of microplastics and heavy metals in the environment. Current methods for detecting microplastics are expensive and time-consuming, so biosensor technology could help track contamination more widely. Better environmental monitoring is an important step toward reducing the microplastic exposure that ultimately affects human health.

Advances in Biosensors for the Rapid Detection of Marine Biotoxins: Current Status and Future Perspectives
This review covers advances in biosensor technology for rapidly detecting marine biotoxins, which are harmful substances produced by marine organisms that threaten both ecosystems and human health through contaminated seafood. While focused on biotoxins rather than microplastics, the optical, electrochemical, and piezoelectric sensor technologies described could be adapted for microplastic detection. Better rapid-testing tools are essential for monitoring the safety of seafood, which is a known pathway for both biotoxins and microplastics to reach humans.
