Australian researchers are developing a new type of nanofibre mesh bandage that attracts bacteria, and will hopefully help to speed up the healing process. The mesh has already been successfully tested on bacterial colonies and engineered skin models in the lab, and the results suggest that bacteria will choose to move out of a wound and onto the material. In other words, it may be able to help draw infections out of human tissue.
“For most people, wounds heal quickly. But for some people, the repair process gets stuck and so wounds take much longer to heal. This makes them vulnerable to infection,” lead researcher Martina Abrigo, from Swinburne University of Technology, said in a press release. “We hope this work will lead to smart wound dressings that could prevent infections. Doctors could put a nanomesh dressing on a wound and simply peel it off to get rid of the germs. “The nanofibre mesh is created using a technique called electrospinning, in which polymer filaments 100 times thinner than a human hair are squeezed out of an electrified nozzle.
The resulting fibre is then coated in compound called allylamine, which Abrigo has found makes a range of different bacteria quickly attach to it.So far, Abrigo and her team have tested the mesh over the top of films of Staphylococcus aureus, which is often involved in chronic wound infection, as well as E. coli, and showed that the bacteria quickly transferred onto the fibres.
