work description

What colors does DNA have? None, and all. The joint work of artist Lucia Covi with scientist from Nanoscience Institute CnrNano produced a series of images of the nanoworld, such as the DNA molecules in this image captured with an Atomic Force Microscope. Ehttp://blowup.nano.cnr.it/ Infact also the DNA molecule belongs to the nanoworld. DNA is actually a nanowire, very resistant and capable of transporting information, and has above all peculiar properties of self-assembling and self-recognizing, developed in thousands of years of evolution, that might be exploited to build up nanocircuits. Researchers are, for example, investigating its use as a component for electronics. Studies are performed on DNA filaments covered with metal atoms, such as those depicted in the image, to obtain conductive nanowires. Nano-bioelectronics studies how to build electronic systems out of biological molecules in order to gain architecture more profitable than the silicon-based traditional ones.
