About Au Particles
Gold Particles endows a series of monodisperse polycrystalline nanocrystals with a spherical shape with an average diameter ranging from 10 - 50 nm. Citrate-capped nanoparticles are very stable. Citrate-capping can be easily functionalized with various ligands, such as peptides, DNA, and antibodies.
Exceptional Physical and Chemical PropertiesAu particles boast a high density (19.3 g/cm3), outstanding electrical and thermal conductivity, and impressive resistance to acids and alkalis. Their melting and boiling points are 1064C and 2856C, respectively, making them suitable for demanding applications. Their customizable particle size allows flexibility, from nano to micron scale, to meet diverse industrial requirements.
Versatile Applications Across IndustriesGold particles are extensively used in electronics, medical diagnostics, catalysts, sensors, scientific research, and specialty coatings. Their unique properties enable precise conductive pathways in devices, enhance medical imaging techniques, expedite chemical reactions, and provide durable, attractive coatings with longevity and reliability.
Safe Handling and Long-Term StabilityWhile bulk gold is considered non-toxic, nanoform gold particles require proper safety measures during handling. For optimal longevity, Au particles should be stored in tightly sealed containers, in a cool, dry environment to maintain purity and stability. Their insolubility and low moisture content support extended shelf life and easy storage logistics.
