“…Such systems have also been used to study the fluorescence of bioaerosols; and other fluorescent particles in the laboratory (e.g., [29,32,10,97]), and to make continuous reagentless fluorescence measurements of atmospheric aerosols on several continents (e.g., [78,79,65,68,71,72,34,24,25,26,101,100,80,104]). Pan et al [67] summarized how to select the illuminating light source (laser, light-emitting diode (LED), or flash lamp); choose the most suitable detector (charge-coupled device (CCD), intensified CCD (ICCD), linear arrays of avalanche photodiodes, or multianode photomultiplier tube (PMTs)); and generate the test bioaerosol. They also reviewed the instrumentation of a few well-known detection systems.…”
