Nature Materials, the light-activated nanoparticles killed 92 percent of resistant bacterial strains, including Staphylococcus, E. Coli and Salmonella, while keeping healthy cells completely unharmed.
“By shrinking these semiconductors down to the nanoscale, we’re able to create highly specific interactions within the cellular environment that only target the infection,” Prashant Nagpal, senior author of the photo activation study at UC Boulder said.
Quantum dots provide the perfect weapon with which to match the adaptability of bacteria. They provide a solution that is both flexible and effective.
The dots are 20,000 times smaller than a single strand of human hair. They act as semiconductors that hold all of their electrons tightly within three spatial dimensions: forward/backward, up/down and left/right.
