ABSTRACT:
Airborne particles are impacted on a collection surface, analyzed, and then the collection surface is regenerated. Thus, the same collection surface can be used in numerous cycles. The analysis can be focused on one or more properties of interest, such as the concentration of airborne biologicals. Sensors based on regenerative collection surfaces may be incorporated in many networks for applications such as building automation.
