Origami isn’t usually thought of as a weapon – but it can be deadly when it is made of DNA. Tiny devices made from intricately folded DNA strands can boost the potency of antibacterial chemicals by bringing individual molecules into direct contact with microbes.
When tested on two common kinds of bacteria, the folded DNA slowed their growth rate. Ioanna Mela at the University of Cambridge says the approach could be directed against any kind of microbe. “This is proof of principle,” she says.
DNA …
