Tiny rocketlike particles that move around on their own in a hydrogen peroxide solution can detect trace amounts of the lethal toxin ricin within minutes (ACS Sens. 2016, DOI: 10.1021/acssensors.5b00300). They could someday provide a quick, easy way to detect the bioterrorism agent in food and water samples without having to bring them back to a lab. The particles, made of graphene oxide and platinum, . . .
