Molecular Manufacturing: A Machine Built out of DNA
Technology Review (MIT)
Vol. 108, Num. 4
In each cell, proteins are manufactured by ribosomes. The complexity and scale of such tiny biological processes have been beyond reach -- until now. New York University researchers Shiping Liao and Nadrian Seeman have created a programmable nanoscale machine that can weld together DNA molecules. In future, this machine could help make improved pharmaceuticals or biochemical materials.
