Xinhua News Agency, Canberra, September 14 (Reporter Zhang Jianhua) A research team led by the University of South Australia and RMIT University has invented a nanoscale bactericidal material that is expected to be used to make wound dressings to prevent or treat wound infections caused by drug-resistant bacteria. .
This research uses black phosphorus nanosheets as a material to treat infections and promote wound healing, which can effectively resist a variety of drug-resistant bacterial infections, including Staphylococcus aureus, known as “superbugs”. Preclinical studies have shown that this new material can effectively kill more than 99% of bacteria without harming other cells in biological models; it has been shown to be as effective as antibiotics in eliminating infection and accelerating wound healing, and the wound can be healed in 7 80% healing within days.
According to reports, black phosphorus is the most stable phosphorus element. It exists naturally in many minerals. It has an ultra-thin layered crystal structure and is easily degraded by oxygen, making it an ideal material for killing microorganisms. As the black phosphorus nanoflake material decomposes, its surface reacts with air to produce reactive oxygen species, which have sterilizing properties.
Zlatko Kopetsky, the main leader of the study and a senior researcher at the University of South Australia, said that this new treatment is as effective as the antibiotic ciprofloxacin in eliminating wound infections, and he looks forward to transforming this research into chronic Clinical treatment of wounds.
