1. A method of detecting the attachment of an organic species onto the surface of one or more nanoparticles within a sample comprising the nanoparticles and the organic species, wherein the method comprises performing concurrent scans of the fluorescence excitation and emission wavelengths for the nanoparticles within the sample and determining an intersect between the excitation and emission wavelengths yielding the highest fluorescence intensity, the intersect indicating the presence or absence within the sample of a nanoparticle complex comprising the one or more nanoparticles having the organic species attached to the surface of the nanoparticle.
