What is MRSAid™?

MRSAid™ is a novel, non-antibiotic system for nasal bacterial decolonization to reduce the incidence of hospital-acquired infections (HAI’s). MRSAid™ is based on the technology “Photodisinfection”, and consists of the application of a topical photosensitizer solution in the nasal passages of individuals colonized with a pathogenic bacteria such as methicillin-resistant Staphylococcus aureus (MRSA).

This solution is subsequently activated locally using non-thermal visible light energy. The treatment is painless, does not lead to…



MRSAid™ treatment is based on the platform technology “Photodisinfection”. Photodisinfection involves the use of non-thermal light energy to activate a liquid photosensitizer formulation, leading to the generation of reactive oxygen-based molecules that are lethal to bacterial cells. These molecules are extremely short-lived, and destroy bacterial membranes via lipid peroxidation while causing little or no damage to surrounding tissue. Photodisinfection has been shown to be effective against a wide range of bacteria (including biofilm forms), as well as…
