Abstract: The present invention relates to barcodes coated with metal nanoshells and to methods of making the metal nanoshell-coated barcodes. The metal nanoshell-coated barcodes of the present invention have applications in detection systems, including multiplex detection systems.

Abstract: A composition including a mixture of: (a) first nanoparticle carrier vehicles loaded with an active ingredient for treating or preventing a disorder (therapeutic nanoparticles), and (b) second nanoparticle carrier vehicles without the active ingredient (decoy nanoparticles). Also method of treating or preventing a disease, disorder or condition comprising administering to a human subject in need a dose of a composition having nanoparticles containing an active ingredient effective to treat or prevent the disease, disorder or condition. The dose is in terms of number of nanoparticles, and the nanoparticles is one of gold nanoparticles, liposomes, silica nanoparticles, micelles, hydrogels or polymeric nanoparticles. The number of nanoparticles in the dose is of at least one and one-half (1.5) quadrillion (1015) nanoparticles.
