The use of light could detect bacteria faster than the current laboratory-based detection system. Sheila MacNeil and researchers at Sheffield University have identified a mothod that could ascertain the presence of bacteria in less then a minute by using light, reported the only edition of BBC News. The technology could have wide applications in would healing, counter-terrorism and screening patients ofr MRSA (bacterial)infection,the experts said. The scientists are developing a portable kit in which specially designed molecules emit a light signal when bound to bacteria .
