Biology News: Cyborg cells sense humidity

Biology News: Cyborg cells sense humidity: "Cyborg cells sense humidity"

"Living bacteria have been incorporated into an electronic circuit to produce a sensitive humidity gauge.

"The device unites microbe and machine, taking advantage of the properties of both to make for a supersensitive sensor.

"'As far as we know, this is the first report of using microorganisms to make an electronic device,' says Ravi Saraf, a chemist from the University of Nebraska, Lincoln, who developed the 'cellborg' with his student Vikas Berry.

"This is essentially a first step towards a biological computer, and would have many applications," says Steve Ripp, a biotechnologist at the University of Tennessee, Knoxville."
