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.
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.
