Researchers have created a DNA spider that can do a simple task —
pick up and carry a gold nanoparticle. To do this, the spider’s arm binds to a DNA “leash” on a nanoparticle, detaches it from the station and ferries the cargo away (top). Atomic force microscopy (bottom) shows three separate nanoparticles (purple) as they are collected by the spider.
