Detection of Biological and Non-Biological Aerosols via Fluorescence and Surfactant on Droplets via Harmonic Generations

摘要

For the entire grant period, the objective has been to use optical diagnostic techniques to characterize the airborne particles. Ideally, the particles in the ambient, with or without deliberate disbursement, need to be classified and, if possible, be identified. Conditioned on the classification of particles, that randomly transit through the sample volume, the particles would or would not be deflected to another location where the particles would be subject to series of biochemical-related identification. Our challenge is to develop optical techniques that could serve as the preliminary screener of every airborne particle that randomly transits (at 1 - 10 m/s) through the sample volume. The challenge is to discriminate the bio- from the non-bio-aerosols within a tune short enough to trigger the particle deflector and possibly to set off an alert alarm.
