Abstract
A spectral reflectance imaging device for detecting nanoparticle exosome biomarker targets includes an illumination source that illuminates a substrate with a plurality of separate wavelengths of incoherent light. The substrate includes an oxide layer and a binding agent to selectively bind nanoparticle exosome biomarker targets to the substrate. An imaging device bindings the light reflected from or transmitted through the substrate and an image processing system detects the nanoparticle exosome biomarker targets a function of the change in reflective properties of the substrate.
