Researchers develop bacteria-fighting wound dressing made with the help of crustaceans
A new type of wound dressing could improve thousands of people's lives, by preventing them from developing infections. The dressing, a type of compression held in place by a bandage, uses an antibacterial substance formed from the shells of crustaceans like shrimps. It is described in a paper published in the May issue of Radiation Physics and Chemistry.

Antimicrobial resistance is becoming a worldwide health threat. A recent report by the Review on Antimicrobial Resistance, commissioned in 2014 by then UK Prime Minister David Cameron and led by economist Jim O'Neill, warns that antimicrobial resistance could kill 10 million people each year by 2050, dwarfing even the number of estimated deaths from cancer. Because of this, preventing infection has never been more important.
"We developed a composition where chitosan is dissolved in lactic acid and, when added to the regular composition of the dressing, it does not adversely change its ability to cross-link during manufacturing or alter its mechanical and functional properties," said Dr. Wach. "The new hydrogel wound dressing is biologically active."
