1. An airborne biological particle monitoring device that collects particles floating in air comprising: a processor; a camera sensor configured to be controlled by the processor; an illumination source configured to be controlled by the processor; and a quantum-dot illumination source configured to be controlled by the processor, wherein the camera sensor captures at least a first image of the particles when the collected particles are illuminated by the illumination source, and captures at least a second image of the particles when the collected particles are illuminated by the quantum-dot illumination source, wherein the processor is adapted to analyze the first and second images to identify the collected particles, and wherein the quantum-dot illumination source comprises: a light emitting element; and a film, comprising quantum dots, and positioned to receive first light from the light emitting element and convert the first light into second light, wherein the second light illuminates the collected particles for the second image.
