A serious challenge for environmental protection in the fast-growing nanotechnology industry is the development of new methods for effective removal of nanoparticle contamination, which may pose hazards to humans, from air. We will develop new laser-based methods for effective capture and removal of nanoparticulate pollutants from air, which will find wide-spread application in developing ecologically clean and health-safe environments for the Australian and world-wide nanotechnology industry.
