Light to detect wound infection
‘UK scientists have identified a way of using light to rapidly detect the presence of bacteria. [..]
The team have spent five years designing special large molecules, or polymers, which can bind to cells.
Once bound the polymer changes shape and emits a light signal.
This can either be a coloured light, such as a red glow, or a light that is naked to the visible eye but can be detected under a fluorescent lamp, depending on the type of polymer that is used.’
