Scientists at RMIT have developed a new antibacterial fabric that kills infectious bacteria like E Coli in 10 minutes. This discovery could be a game changer for hospitals that battle the risk of infectious bacteria on a daily basis as Secondary infections are a serious and potentially deadly complication for hospital patients.
“There is potential for special bedding, linens and surgical aprons on which bugs and bacteria do not grow, so we can maintain an infection-free environment in our healthcare settings,” said Associate Professor Vipul Bansal. “We may also have dressings and Band-Aids that can kill bacteria in the wound, resulting in faster healing. These will all have a major impact on the cost of the Australian healthcare system.” The next generation of smart textiles will be free from bacteria and odour and have a range of potential applications from clothing – putting an end to smelly socks – to sporting gear and uniforms.
The scientists found organic materials with semiconductor properties can have superior antibacterial effects over metal salts of silver which are already known for their antibacterial properties. To test the concept, they grew nanowires on a fabric which confirmed the antibacterial properties of Ag-TCNQ (tetracyanoquinodimethane). The results were recently published in the prestigious journal Advanced Functional Materials and featured on the journal’s cover.
Socks that don’t smell? My wife can’t wait for that!
