PCO has started R&D on the capabilities of near-infrared light. Currently there is evidence to suggest that certain frequencies of light may help in the regeneration of cell growth. Industries that may be interested in this technology include: the medical field, hair care and cosmetics, and the pharmaceutical field amongst others. Evidence has shown that certain frequencies of light aid in the sterilization of tools or surfaces, because the exposure of these items to the near-infrared light kills any living bacteria. here!
