Can we finally get rid of superbugs? Or will the bugs just develop a resistance to the quantum dots? Will we elimite any more diseases like smallpox? http://www.huffingtonpost.com/entry...perbug-infections_us_569eb601e4b00f3e98634e5b Tiny Quantum Dots May Spell Doom For Deadly Superbug Infections Scientists say the light-activated nanoparticles wipe out infectious bacteria without harming healthy cells 01/20/2016 02:49 pm ET David Freeman Senior Science Editor, The Huffington Post ILEXX VIA GETTY IMAGES Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium responsible for several difficult-to-treat infections in humans. Does nanotechnology hold the key to stopping antibiotic-resistant bacteria and the deadly infections they cause? Scientists in Colorado think it just might. They've developed light-activated nanoparticles -- each roughly 20,000 times smaller than the thickness of a single human hair -- and shown in lab tests that these "quantum dots" are more than 90 percent effective at wiping out antibiotic-resistant germs like Salmonella, E. coli and Staphylococcus. "In our study, we tailored these quantum dots so they can selectively kill these 'superbugs' without affecting other host mammalian cells (or human cells)," Dr. Prashant Nagpal, assistant professor of chemical and biological engineering at the University of Colorado at Boulder and a leader of the research, told The Huffington Post in an email. "This means, after more careful clinical trials, we can simply administer these dots to patients with infections and it can cure the infection without potential effects (or side effects) for healthy host cells." If Nagpal is right, that would be a very big deal.
