Touch nanosensor zOmg.

Scientists have developed a high resolution touch nanosensor… A thing that can sense things.

Made of incredibly thin layers of Gold (Au) and Cadmium Sulfide (CdS), seperated by equally thin layers of insulation, these nanosensors basically conform to the shape of the surface they're on, accurate to about 10 microns (10 millionths of a metre). An electrical current is then applied to the sensor, which makes it produce light, then, by the concentration of light or current in each area, the feel of the surface can be ascertained, which can be translated into a high resolution image of the surface. This could have application in cancer surgery, for example, when the surgeon does not want to cut too far, in order to avoid unnecessary damage to organs, but wants to completely get rid of the cancer. This nanosensor could be used to feel whether cancer cells are present.

Thanks to the chemical construction of the nanosensor, it is strong enough to hold together, but weak enough to be easily adjustable. It is also self-assembling at room temperature. Impressive.
