Lasers that target and kill antibiotic-resistant bacteria
Infections are one of the most common complications that occur after surgeries, affecting between 2 to 4 percent of patients in the U.S. and killing thousands each year. Currently, hospitals sterilize equipment using disinfectants, ultraviolet (UV) radiation, and high heat, all of which are too dangerous to be used on patients. Lasers that can target and kill bacteria without exposing a patient to harmful chemicals or radiation could prevent thousands of infections each year. Plus, these bacteria-killing lasers could be the key to fighting antibiotic-resistant bacteria, a growing health crisis that kills millions of people annually.
