Congratulations to Xu, Olivia, and Rong for their collaborative paper with the Verduzco group! “Amplification of enzymatic and microbial fuel cells using organic electrochemical transistors” demonstrates interesting approaches to building thin-film sensing devices by coupling OECTs electronically with either an enzymatic fuel cell or microbial fuel cell. By amplifying microbial currents and enhancing signal quality, their simple and compact living device using synthetically engineered bacteria can detect arsenite in water! Read about it here.
