Nanothin antimicrobial coating could prevent and treat potentially deadly infections. Researchers have developed a new superbug-destroying coating that could be used on wound dressings and implants to prevent and treat potentially deadly bacterial and fungal infections. The material is one of the thinnest antimicrobial coatings developed to date and is effective against a broad range of drug-resistant bacteria and fungal cells, while leaving human cells unharmed. Antibiotic resistance is a major global health threat, causing at least 700,000 deaths a year. Without the development of new antibacterial therapies, the death toll could rise to 10 million people a year by 2050, equating to $US100 trillion in health care costs. While the health burden of fungal infections is less recognized, globally they kill about 1.5 million people each year and the death toll is growing. An emerging threat to hospitalized COVID-19 patients for example is the common fungus, Aspergillus, which can cause deadly secondary infections.The new coating from a team led by RMIT is based on an ultra-thin 2D material that until now has mainly been of interest for next-generation electronics.Studies on black phosphorus (BP) have indicated it has some antibacterial and antifungal properties, but the material has never been methodically examined for potential clinical use.
