Description

Description générale

Gold(Au) is a yellow noble metal known for its lustrous appearance and highresistance to corrosion. With a melting point of 1,063 °C, gold is one of themost malleable and ductile metals, making it ideal for various applications.Our high-purity gold powder is characterized by its purity of 99.9% on a tracemetals basis and is available in a fine powder form with particle sizes <10μm. Gold is widely used in electronics, dental materials, and as a catalyst invarious chemical reactions. Gold powder is a key material in the synthesisof gold nanoparticles, which have applications in sensors, imaging, and ascomponents in nanocomposites. The unique optical properties of goldnanoparticles are exploited in various nanotechnology applications.

Application

Gold particles were used to coat Calcium-green-1 dextrans conjugated dye, for ballistic dye loading via gene gun.
