Researchers Develop Chemical Switch to Control Biomolecular Motor

Researchers have created a tiny motor that they can turn on and off at will, bringing scientists one step closer to using such devices to repair cellular damage, manufacture medicines and attack cancer cells. As reported in this month’s Nature Materials, the researchers have developed a chemical switch that gives them control over a biomolecular motor just 11 nanometers, or 11 billionths of a meter, in size ? hundreds of times smaller than the width of a human hair.
