The dots are particles just 100 nanometres across. “There’s nothing magical about it,” says Bob Carr, chief technical officer of Nanosight, based in Salisbury, UK, which developed the device. Dubbed Halo, it can be attached to any light microscope to let you view moving particles as small as 10 nanometres. And Halo could become more than a curiosity, says Carr, with applications from detecting bioweapons to quality control in paints,
