Abstract
A new seedless synthesis of anisotropic nanoscale gold nanoflower (AuNF) particles uses bidentate thiolate ligands to protect the nanoparticle surface and a combination of reagents (for example, ligand, ascorbic acid, and hydroxide) to synthesis AuNF with controlled size and anisotropic properties. Compared to prior art gold nanospheres, AuNF produced approximately a 15-fold improvement in a drug delivery assay.
