Researchers in New Zealand have discovered that a dual-light technique can deactivate a strain of E. coli that is resistant to antibiotics. By combining blue light-emitting diodes and ultraviolet light at specific wavelengths, the researchers were able to disrupt the activity of the microbes without causing harm to human health. The technique has the potential to be used in various applications, such as sanitizing hospitals and food preparation facilities. However, the researchers also found that the E. coli strain can develop tolerance to light after repeated exposure, which requires further investigation.
