The use of light activated antimicrobials to prevent catheter related infection

点击翻译按钮获取中文摘要

This project is focussed on reducing catheter acquired infection or CAI. These infections are widespread in the NHS and are particularly prevelant in newborns and the elderly. Our project seeks to reduce these infections through a new approach that uses a light source and a new class of catheter. This catheter has embedded dye molecules that under the action of light produce species that are toxic to bacteria. These catheters are self sterilising and most importantly show the ability to resist the biofilm formation that is the precursor to infection. It has been determined that catheter born infections are the most common cause of hospital acquired infection in the UK.
