Abstract: Embodiments of the present invention are directed to systems and methods for continuously sampling particles from air. In one embodiment, a system for continuously sampling particles from air may include: an airflow system configured to continuously draw air including airborne particles into the system; a photophoretic trap that uses photophoretic forces of a laser beam to trap one or more of the airborne particles from the drawn air; a measurement device configured to measure one or more properties of the trapped one or more airborne particles; and a controller configured to repeatedly trap, measure and release one or more airborne particles.
