David O'Connor - PBAP in the Atmosphere

It is well-known that general seasonal respiratory problems may be caused by a specific pollen or spore type. Currently the identification and detection of Primary Biological Aerosol Particles (PBAP) is challenging and often limited to laborious staining and optical counting methods. The Centre for Research into Atmospheric Chemistry at UCC, is pioneering a new technique for determining airborne PBAP using a single-particle fluorescence sensor. The instrument provides real-time information on size, shape and whether or not a particle is biological in nature. David O'Connor describes work undertaken during his PhD on PBAP in the laboratory and field.
