This technology is derived from photodynamic therapy and uses a photosensitizer molecule as the active agent for long-lasting, anti-microbial effect and air purification. This photosensitizer relies on the activation by light irradiation to produce active oxygen and reactive oxygen species (ROS) which can kill bacteria, viruses, fungi and mold, as well as disintegrate volatile organic compounds (e.g. formaldehyde) on contact.
The molecule is a conjugated compound based on an extraction from plant-based polylysine and an edible mineral. This technology disrupts the traditional use of toxic chemicals to kill microbes by replacing it with a safer, reactive oxygen generating catalytic molecule. It is effective against microbe contamination, minimising transmission of diseases. The technology has been formulated into various applications such as paints, textiles, hygiene products and polymeric films to name a few.
