A new wound healing spray will help treat wounds without the use of antibiotics. It kills bacteria with
Scientists have previously studied peptides fordestroying bacteria. The problem is that they quickly break down upon contact with blood or other body fluids. However, scientists from Chalmers University of Technology in Sweden have found a “workaround.”
They attached peptide moleculesto hydrogel microparticles with a special structure. It protects them from blood, but at the same time helps them destroy bacteria by disrupting the protective outer membranes of bacteria and they do not develop resistance to antibiotics.
Scientists have already tested the new sprayin the laboratory: it was found to kill 99.99% of bacteria on contact with a wound, including antibiotic-resistant types such as MRSA (methicillin-resistant Staphylococcus aureus). Moreover, it remained effective for approximately 48 hours.
Scientists are now exploring the possibility of usingspray for coating medical implants to prevent infections. They have already tested it on silicone, which is commonly used for catheters.
“The substance in this wound spray is absolutelynon-toxic and does not affect human cells, scientists explain in a press release from Chalmers University of Technology. — Unlike existing bactericidal sprays, it does not interfere with the body’s healing process. Materials that are simply sprayed onto a wound kill bacteria in a shorter time.”
