Paper Abstract

Sensors that are able to provide reagent-free, continuous monitoring for potential bio-aerosol hazards are required in many environments. In general, increasing the number of optical and spectroscopic properties of individual airborne particles that can be measured increases the level of detection confidence and reduces the risk of false-positive detection. This paper describes the development of relatively low-cost multi-parameter prototype sensors that can monitor and classify the ambient aerosol by simultaneously recording both a 2x2 fluorescence excitation-emission matrix and multi-angle spatial elastic scattering data from individual airborne particles. The former can indicate the possible presence of specific biological fluorophores in the particle whilst the latter provides an assessment of particle size and shape.
