Anti-bacterial light could help keep a clean clinical laboratory

A new type of LED lighting could help to keep clinical laboratory environments free from pathogens by bathing them in anti-bacterial light.

Developed at the University of Strathclyde, the system is based around a narrow range of the visible light spectrum capable of killing infections including C difficile and MRSA.

However, the team, which includes microbiologist John Anderson, has adapted the usually-violet light as part of an LED-based luminaire that emits white light.

Professor Anderson says: "The technology kills pathogens but is harmless to patients and staff which means, for the first time, hospitals can continuously disinfect wards and isolation rooms."

Designed for use in hospitals, the lighting could also achieve a significant reduction in the level of pathogens in a clinical laboratory research environment.

The University of Strathclyde says its aim is to contribute towards Scotland's social cohesion and quality of life while helping to advance those issues nationally and globally.
