Controlled electrochemical fabrication of large and stable gold nanorods with reduced cytotoxicity.

ABSTRACT: Gold nanorods (GNRs) are valued for their tunable surface plasmon resonance (SPR) and unique optical properties, but precise control over their size and shape remains challenging. Current synthesis techniques often yield polydisperse samples and require high concentrations of cytotoxic surfactants, limiting their biomedical applications. In this study, we introduce a novel electrochemical synthesis method that offers precise control of GNR characteristics by leveraging open circuit potential (OCP) data from colloidal synthesis. This approach involves the electrochemical growth of gold nano-seeds immobilized on fluorine-doped tin oxide (FTO) substrates, using physical vapor deposition (PVD) followed by thermal annealing to generate the Au seeds. This eliminates the need for seed solutions a
