‘Quantum dots’ mess with bacteria’s defenses, allowing antibiotics to work
Antibiotics may have a new teammate in the fight against drug-resistant infections.
Researchers have engineered nanoparticles to produce chemicals that render bacteria more vulnerable to antibiotics. These quantum dots, described online October 4 in Science Advances, could help combat pathogens that have developed resistance to antibiotics (SN: 10/15/16, p. 11).
“Various superbugs are evolving too rapidly to be counteracted by traditional drugs,” says Zhengtao Deng, a chemist at Nanjing University in China not involved in the research. “Drug-resistant infections will kill an extra 10 million people a year worldwide by 2050 unless action is taken.”
In the study, antibiotics spiked
