Yes, blue laser light at approximately 470 nm has been shown in studies to exhibit antimicrobial properties and can inhibit bacterial growth in vitro. Research has demonstrated that 470 nm light affects bacterial cells by generating reactive oxygen species (ROS) that damage cellular components, thus inhibiting bacterial growth. Studies suggest this effect is particularly relevant for certain bacteria like Staphylococcus aureus and Pseudomonas aeruginosa, which are known for causing wound infections and other complicationsue light at this wavelength has been observed to stimulate fibroblast activity, promoting cellular proliferation and enhancing wound healing. This effect is thought to occur as the light modulates cellular signaling pathways, leading to increased fibroblast proliferation and collagen production, which are key factors in tissue repair and wound closure .
