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.
Mechanical engineers at The Ohio State University built these objects using the long-understood principles of human-sized machine design. They say this approach to building 3-D constructs out of DNA is different from other groups, which are instead trying to build complex, static shapes or mimicking the structure of biological systems.
