Gold Nanoparticle Applications and Characterisation by Nanoparticle Tracking Analysis
Gold nanoparticles are one of the most popular and extensively researched type of nanoparticle.
A Google Scholar search of the term ‘gold nanoparticles’ results in more than 500,000 hits. Applications range from the biological to the material, and include nanomedicine, drug delivery, cancer diagnostics, biological scaffolds, biosensors, contrast agents, catalysts, and chemical-mechanical planarisation (CMP) slurries for the manufacturing of microprocessors.
This wide ranging application space is made possible by their versatile optical properties, compatibility with a variety of surface chemistries, and their well-studied synthesis and preparation.
