The School of Medicine of the University of Hong Kong (HKU) has invented two-dimensional novel antibacterial nano-sheets which can eliminate more than 99.72 percent of methicillin-resistant Staphylococcus aureus (MRSA) in bone tissue.
The study results have been published in Advanced Materials.
MRSA is a common pathogenic bacteria of bone tissue infection (osteomyelitis). In severe patients, the bacteria may lead to amputation or sepsis.
Since the bacterial membrane has been formed in the infection site of the deep bone tissue, the treatment of injecting antibiotics and non-invasive surgery is often ineffective. Excessive use of antibiotics will also damage the innate immune function, and may also induce the emergence of more drug-resistant pathogens….
