Nanomesh helps fight against antibiotic resistance

News

Nanomeshes are being fabricated in a way that makes them effective at delivering antibiotics, a breakthrough that could help in the global fight against antibiotic resistance.

The breakthrough has been made by researchers at Flinders University in Australia and collaborators in Japan. In studying the effectiveness of the nanomesh, two antibiotics, Colistin and Vancomycin, were added together with gold nanoparticles to the mesh, before they were tested over a 14-day period.

Flinders Institute for Nanoscience and Technology Associate Professor Ingo Koeper said 20cm by 15cm pieces of mesh were produced which contain fibres 200nm in diameter.

"In order to deliver the antibiotics to a specific area, the antibiotics were embedded into the mesh produced using a technique called electrospinning, which has gained considerable interest in the biomedical community as it offers promise in many applications including wound management, drug delivery and antibiotic coatings," Koeper said.
