Folding Origami

Caltech researchers have developed simple nanometer-scale electronic circuits out of carbon nanotubes by sticking them to DNA origami in a desired geometric pattern. DNA origami is a type of self-assembled structure made from DNA that can be programmed to form nearly limitless shapes and patterns. It is created from a long single strand of viral DNA and a mixture of different short synthetic DNA strands that bind to and "staple" the viral DNA...
