Quantum Dot Antibiotics Adapt as Fast as Superbugs

Scientists have been creating antibiotics to kill bacteria for nearly 80 years. But some bacteria have evolved resistance to all antibiotics, and making new drugs to fight these superbugs is a long involved process. So scientists at the University of Colorado’s Biofrontiers Institute are developing an “antibiotic” they can update with the click of a keyboard. Shelley Schlender reports on “quantum dot” antibiotics.
