When gold chloride (AuCl₃) and an electron donor such as molybdenum chloride (MoCl₅) are mixed, the donor reduces gold ions to metallic gold atoms. These atoms then initiate the nucleation of ...

Despite the significant progress in the synthesis and application of gold nanoparticles, several challenges remain to be addressed. These include the scalable and reproducible synthesis of AuNPs with ...

Chemists have discovered that tiny gold 'seed' particles, a key ingredient in one of the most common nanoparticle recipes, are one and the same as gold buckyballs, 32-atom spheres that are cousins ...
