The UK has developed a lighting system that "kills" super bacteria

It is understood that the lighting system tested in the intensive care unit of the Royal Hospital of Glasgow in the United Kingdom has been proven to kill super bacteria, including MRSA, E. coli and C-diff (transmitted pathogens) "superbugs".

Developed by the University of Strathclyde, the HINS-optical system claims that the narrow spectrum of visible light from the light purifies the air and exposed surfaces. The system was originally installed in the isolation room of the hospital in 2010. Hospital studies have shown that it significantly reduces bacterial pathogens in the hospital environment compared to cleaning and disinfection.

Michelle McLean, who is trying the lamp, said: "Clinical trials have shown that this technology can help prevent the spread of pathogens and thus improve patient safety. Although HINS-light is relative to methicillin-resistant Staphylococcus aureus Pathogens such as MRSA and C.diff, such as Clostridium difficile, are fatal, but completely harmless to patients and staff, and reduce the need for continuous disinfection and isolation rooms in hospitals."

The HINS emits light at 405 nm, with a shorter wavelength, but slightly longer than the UV, but unlike ultraviolet light, it is still visible to the human eye. Therefore, the system has a purple hue, but the research team combined LED technology. It can produce a formal hospital lighting warm white lighting effect together.

This is not the first time a medical research team has used specific wavelengths of light to control bacteria. In 2000, an independent research conducted by the Science and Technology Group of Imperial College of Science and Technology and the Medical Research of Hammsmith Hospital in London determined that the combination of blue and red light wavelengths can be used to treat effective phototherapy for acne-causing bacteria.

The trials at Glasgow Hospital were conducted by Scott McGregor, a professor at the University of Strathclyde, and his colleagues as well as experts and scholars, clinicians, infection control experts from the National Health Service (NHS) and Glasgow, UK. In collaboration with Scottish University scholars, HINS-Light was named an annual research project in 2011 and won the Times Higher Education Award.
