Danish researchers in world nanotechnology breakthrough

Top science journal Nature reports that Copenhagen University's Nano-Science Center has created the world's first transistor from a single biomolecule

A research team headed by Professor Thomas Bjørnholm at the Nano-Science Center, University of Copenhagen has scored a world first by developing a transistor that consists of a single organic molecule. The breakthrough is reported in the 16 October issue of the prestigious science journal Nature.

 

Prof. Bjørnholm's team linked three electrodes to a single organic molecule and discovered that it functioned as a transistor by switching off one electrode at a time. Researchers at Cornell University in the US have previously created a transistor from a single cobalt atom, but according to Thomas Bjørnholm the organic transistor has the advantage that biomolecules are intrinsically self-organising, and that is the key to building what will one day become an organic computer.

 

In May this year, the Danish state gave DKK 26 million (USD 4 million) research grant to the Nano-Science Center. The aim of the research is to improve transistor stability and to create well defined circuit structures. The news is reported by Computerworld online.
