Photoactive bacteria bait may help in fight against MRSA infections

Researchers are testing whether a light-active version of heme, the molecule responsible for transporting oxygen in blood circulation, may help people infected with MRSA. Photodynamic therapy, or PDT, involves a compound known as a photosensitizer, which can be activated by visible light to kill diseased cells or bacteria. PDT is a clinically proven method for fighting cancer but has not yet been developed for treating MRSA infections. https://www.sciencedaily.com/releases/2018/10/181011173114.htm
