Chemical engineers at the University of Nebraska, Lincoln, have designed and fabricated a humidity sensor made from living bacteria and gold nanoparticles (Angew. Chem. Int. Ed. 2005, 44, 6668). Vikas Berry and Ravi F. Saraf prepared the hybrid nanoelectronic device by depositing gram-positive bacteria on a silicon substrate with lines of gold electrodes.
