Gold Nanoparticles Fight Biofilm on Surgical Mesh

May-29-19 Surgical meshes coated in gold nanoparticles could offer a heat-activated way to combat infection after surgery.

Surgical meshes are used in many procedures, including hernia repair. However, these meshes can become contaminated by bacteria, which then have to be treated with antibiotics.

To offer an alternative to medication—and help slow the rise of drug-resistant bacteria—the team from the Institute of Photonic Sciences developed a mesh with a coating of gold nanoparticles, which will heat up when exposed to near-infrared light. In lab tests on coated mesh infected with S.aureus bacteria, the near-infrared light heated the gold enough to kill most of the bacteria and severely damage the remaining survivors.
