Gold Nanoparticles

Gold Nanoparticles are highly stable, conductive, and optically active nanomaterials widely used in nanotechnology, materials science, catalysis, photonics, and analytical chemistry. These particles, typically ranging from 1–100 nm, exhibit unique surface plasmon resonance, tunable optical absorption, and excellent dispersibility in aqueous and organic media. Gold Nanoparticles can be synthesized in spherical, rod, or core–shell forms and easily functionalized with polymers, thiols, or silica coatings for advanced material integration. Their exceptional conductivity, surface reactivity, and chemical stability make them valuable for sensor fabrication, electronic components, thin-film coatings, and plasmonic devices. Gold Nanoparticles, AuNPs, colloidal gold, metallic nanomaterials, nanogold, gold nanostructures, plasmonic nanoparticles, functionalized gold particles, and noble metal nanomaterials are among the most searched keywords in nanotechnology, surface chemistry, materials engineering, and optical research.
