We disclose a method of tagging pharmaceutical and nutritional products with nanoparticles
which include noble metals. The disclosure describes a plurality of nanoparticles each with
either a different size and/or shape. The nanoparticles of different sizes and shapes are
distinguishable using spectroscopic techniques because each is associated with different
optical properties and have a different spectral signature. The different optical properties are
at least due to the unique size or shape of the nanoparticles. Each of the plurality of …
