Abstract
A particle detection apparatus and method includes an excitation source having a first emission band that excites a sample and a second emission band; a first optical device connected to the excitation source and attenuates radiation emitted in the second emission band; an optical cavity adjacent to the first optical device, which includes a sample excited by radiation from the excitation source; a substrate coupled to the optical cavity and exposed to the radiation from the excitation source; a binding compound coupled to the substrate, which includes a ligand coupled to the substrate; and a capture material coupled to the ligand and capturing the sample; a second optical device connected to the substrate and attenuates radiation emitted in the first emission band; and an optical detector connected to the second optical device and detects radiation emitted in the second emission band.
