Abstract:
The invention is drawn to novel gold nanoparticles that are used in a dual optical method for sensitive and selective detection of antigens. The gold nanoparticle aggregates are synthesized from gold hydrochloride and sulfur salts in an aqueous solution. The aggregates can be selectively sized using a spectral notch filter that results in an improved product with versatile uses. The gold nanoparticles can also be used in improved optical communications devices.
