Scientists have developed a highly sensitive and stable biosensor for detecting ethanol using a microbial biofilm modified with glutaraldehyde, a cross-linking agent that enhances enzyme binding. The study found that applying glutaraldehyde before the microbial consortium in a 1:1 ratio produced the best oxidation response, improving the biosensor’s precision and selectivity, even in food samples. With 93% stability over multiple tests, this biosensor could lead to more accurate and practical ethanol detection, benefiting industries like food safety, pharmaceuticals, and environmental monitoring.

This research aligns with SDG 3 as the biosensor can be used for medical diagnostics and ensuring safer healthcare practices. It also supports SDG 9 by advancing biosensor technology, contributing to scientific innovation in analytical chemistry and biotechnology. Additionally, it relates to SDG 12 by offering a highly selective and precise ethanol detection method, which can enhance food safety and quality control, ensuring that ethanol content in beverages and food products meets regulatory standards.
