ABSTRACT:
The present invention is directed to an aggregate composed of a plurality of nanoparticles of a transition metal and a plurality of cyanine dye molecules that are interacting non-covalently. The nanoparticles are capped with a capping molecule, while the cyanine dye molecule can be cationic, anionic, or neutral cyanine dye. Methods of making such aggregates and for using them in detection of an analyte are also disclosed.
