Bacterial sensors usually rely on emitting light to transfer information about what they're sensing, but that method isn't practical in many settings. That's why most information transmission is done via electricity. And while electricity-emitting bacteria exist, manipulating them into useful sensor s has been quite challenging. Rice University professor Caroline Ajo-Franklin's group, working in collaboration with researchers from Tufts University and Baylor College of Medicine, recently developed a flexible bioelectrical sensor system called electroactive co-culture sensing system (e-COSENS). The study is published in Nature Biotechnology. ...read more read less
