RNA Used As Nano-Scaffolding




Microscopic scaffolding to house the tiny components of nanotech devices could be built from ribonucleic acid (RNA), the same substance that transports messages around a cell’s nucleus, says a research group at Purdue University. By encouraging RNA molecules to self-assemble into 3-D shapes resembling spirals, triangles, rods and hairpins, the group has found what could […]
