Loading ...Using antibiotics to kill bacteria could soon be a thing of the past. Researchers have developed a way to kill bacteria in seconds by using gold nanodisks and light, according to a new study. The discovery could reduce the risk of antibiotics resistance.
“We showed that all of the bacteria were killed pretty quickly…within five to 25 seconds. That’s a very fast process,” author Wei-Chuan Shih, a professor in the University of Houston’s department of electrical and computer engineering, said in a statement.
The scientists, whose work was published in the journal Optical Materials Express on Thursday, managed to create gold nanoparticles by dissolving actual gold into smaller and smaller disconnected pieces. From there, they crafted the nanoparticles into disks.
