Abstract
An airborne biological particle monitoring device collects particles floating in air. The monitor includes a camera sensor, illumination source, and quantum-dot illumination source. The camera sensor captures a first image of the particles when the collected particles are illuminated by the illumination source. The camera sensor captures a second image of the particles when the collected particles are illuminated by the quantum-dot illumination source. The first and second images are analyzed to identify the collected particles.
