ultra-thin electricity-conducting wires produced by postdoctoral researcher Subrata Kundu and associate professor Hong Liang

Kundu and Liang described their fabrication method the journal Advanced Materials.

The process works by sending ultraviolet light on a mixture of strands of DNA, cadmium sulfate and thioacetamide for about six hours. UV light breaks thioacetamide and generates sulfide ions (S2-). Chemical changes generated by the UV light allow the cadmium sulfate molecules to bind to the DNA. The resulting nanowires, which is 1000 times thinner than a human hair, conduct electricity and could be used in nano-scale electronic devices like small chips to make tiny computer or medical devices.
