Now this is pretty weird stuff that University of Nebraska scientists just figured out. Here is what they did:
Scientists first coated a silicon chip with a layer of live Bacillus cereus bacteria. Some of the long, rod-shaped microbes lodged between two etched electrodes on the chip’s surface, forming a bridge. The chip was then washed in a solution containing tiny gold particles, each one about 30 nanometers across.
This what the weird-assed gold cellborg can do:
The cellborg sensor is extremely sensitive: a drop from 20 percent to zero humidity results in a 40-fold decrease in current flow. In humidity sensors that are solely electronic, the decrease is only 10-fold.
If they could get it to reproduce itself then we will have some science fiction style stuff going on.
