Special Issue Information

Dear Colleagues,

Electrochemical sensors and biosensors represent a promising solution for the affordable, quick, and decentralized testing of complex samples and are accessible even to those with minimal training. They hold significant potential for food and environmental analysis, but several technical and commercial challenges must first be addressed in order to fully realize their benefits.

This Special Issue of Biosensors, titled “Sensors for Environmental Monitoring and Food Safety”, aims to showcase the latest advancements in this dynamic field. We invite you to contribute research that highlights recent developments and applications in this field. Our focus includes both electrochemical and non-electrochemical sensors, utilizing classical and advanced techniques such as enzymes, antibodies, DNA, aptamers, molecularly imprinted polymers, and nanotechnology. We welcome submissions in the form of reviews, communications, and research articles.

Heavy metal contamination in livestock and poultry farm wastewater poses significant risks to both the environment and human health, so it is critical to accurately and rapidly quantify heavy metal ion concentrations in water. This research develops a bioelectric active hydrogel sensor for detecting heavy metal ions in livestock wastewater. The sensor integrates microbial surface display technology with graphene hydrogel, displaying glucose oxidase (GOx) on the surface of yeast cells, and covalently incorporating it into the graphene hydrogel through the bio-reduction activity of metal-reducing bacteria, enhancing its electrochemical performance. The sensor demonstrates excellent sensitivity and stability in detecting Cu2+, with a detection limit for Cu2+ of 17.0 µM. This sensor is also applicable for detecting Zn2+ in wastewater. When various heavy metal ions coexist in the solution, they exert a more pronounced inhibitory effect on enzyme activity. Consequently, the sensor can be employed to assess the overall heavy metal content in water samples. In the detection of Cu2+ in real livestock and poultry wastewater, the recovery rate of the graphene hydrogel electrode ranged from 88% to 106.5%, indicating that the sensor holds significant potential for application in actual sample analysis.
