Congratulations to Xu (newly minted Assistant Professor at Texas A&M University!) on her publication of “Multichannel bioelectronic sensing using engineered Escherichia coli“ in Nature Communications. This innovative work expands the number of toxins a single cell can sense and signal, and conveniently encodes the output into a computer-readable, binary signal. Exploiting the different redox potentials of extracellular electron transfer mechanisms allowed Xu to differentiate signals from arsenite and cadmium-regulated DNA circuits.
