Outside Back Cover: A Programmable and Printable Microbial Bioelectronic Sensor for Real‐Time and Targeted Pollutant Monitoring in Water

In the Research Article e1144662, Yi-Xuan Wang, Zhi-Xiang She, Yang Mu, and co-workers demonstrate a programmable microbial bioelectronic sensor for real-time pollutant monitoring in water. Engineered Shewanella oneidensis couples target recognition to extracellular electron transfer, converting pollutant signals into electrical outputs. Encapsulation within a printable hydrogel and integration into a biomimetic fractal bioelectrode accelerate mass transport, enabling rapid, selective sensing with wireless readout.
