Researchers at KAUST (King Abdullah University of Science and Technology) in Saudi Arabia, not to be confused with KAIST (Korea Advanced Institute of Science and Technology), have developed a special nanoparticle coating that can be used to give the surfaces of medical devices antibacterial properties.
The coating is made of gold nanoclusters containing lysozyme enzymes, an antibacterial agent, fused into a polymer matrix. The nanoparticles also contain kanamycin, an antibiotic.
