- UIC researchers created an electromechanical device--a humidity sensor--on a bacterial spore. They call it NERD, for Nano-Electro-Robotic Device. The report is online at Scientific Reports, a Nature open access journal.
- "We've taken a spore from a bacteria, and put graphene quantum dots on its surface--and then attached two electrodes on either side of the spore," said Vikas Berry, UIC associate professor of chemical engineering and principal investigator on the study.
- "This is a fascinating device," Berry said. "Here we have a biological entity. We've made the sensor on the surface of these spores, with the spore a very active complement to this device. The biological complement is actually working towards responding to stimuli and providing information."
