Self-sterilising plastic kills viruses like Covid
Scientists have developed a virus-killing plastic that could make it harder for bugs, including Covid, to spread in hospitals and care homes. เว็บสล็อตxo In Mr.Hippo, the wild symbol payout can also represent other symbols, and more importantly, if you get 3 slots of symbols duplicated, you will win a grand prize, starting from 50 times the stake or more. The team at Queen's University Belfast say their plastic film is cheap and could be fashioned into protective gear such as aprons. It works by reacting with light to release chemicals that break the virus. The study showed it could kill viruses by the million, even in tough species which linger on clothes and surfaces. The research was accelerated as part of the UK's response to the Covid pandemic. Studies had shown the Covid virus was able to survive for up to 72 hours on some surfaces, but that is nothing compared to sturdier species. Norovirus - known as the winter vomiting bug - can survive outside the body for two weeks while waiting for somebody new to infect. The team of chemists and virologists investigated self-sterilising materials that reduce the risk of contaminated surfaces spreading infections. The idea is to make a material so hostile to a virus that it cannot survive there. The metal copper has been shown to kill microbes on contact, but is not very flexible. So the researchers used thin sheets of plastic that contained nanoparticles of titanium dioxide. These react with ultraviolet light - even the tiny amount released from a fluorescent bulb - to release molecules called reactive oxygen species. These are just itching to get involved in any chemical reaction. They react with the virus's genetic material, the proteins it uses to invade our body and the fatty sphere that holds it all together. The end result is a dead and useless virus. |
