    Abstract

    Inline holographic video microscopy's resolution for single particle characterization is fine enough to detect molecular-scale coatings on colloidal surfaces, without requiring staining or fluorescent labeling. We demonstrate this approach to molecular binding assay by detecting the binding of avidin to biotinylated polystyrene spheres.
