Puny pixel rate in your digicam or mobile phone?

Call the researchers at UCSF and tell them to get the modified E. coli camera sensor ready...

light sensitive to an equivalent of 100 megapixels per square inch.

Proof of the power of noodly appendages, clearly.

A dense bed of light-sensitive bacteria has been developed as a unique kind of photographic film. Although it takes 4 hours to take a picture and only works in red light, it also delivers extremely high resolution.

The “living camera” uses light to switch on genes in a genetically modified bacterium that then cause an image-recording chemical to darken. The bacteria are tiny, allowing the sensor to deliver a resolution of 100 megapixels per square inch.

To make their novel biosensor, Chris Voigt’s team at the University of California in San Francisco, US, chose E. Coli, the food-poisoning gut bacterium. One of the reasons for that choice is that E. Coli does not normally use light - photosynthesising bacteria could have used light to prompt other, unwanted, biological processes.

The researchers used genetic engineering techniques to shuttle genes from photosynthesising blue-green algae into the cell membrane of the E. coli. One gene codes for a protein that reacts to red light. Once activated, that protein acts to shut down the action of a second gene. This switch-off turns an added indicator solution black.

As a result, a monochrome image could be permanently “printed” on a dense bed of the modified E. Coli.

Heheh. Every time I see the FSM graphic i get a good laugh out of it. I think instead of putting fish with feet stickers on the back of their cars, people ought to start putting that on there.

...into the light of a dark black night.

If you build it... they will...
