DNA origami could lead to nano 'transformers' for biomedical applications
Columbus OH (SPX) Jan 06, 2015
If the new nano-machines built at The Ohio State University look familiar, it's because they were designed with full-size mechanical parts such as hinges and pistons in mind. The project is the first to prove that the same basic design principles that apply to typical full-size machine parts can also be applied to DNA--and can produce complex, controllable components for future nano-robots. In a paper published this week in the Proceedings of the National Academy of Sciences, Ohio State mech ... read more
