Anisotropic gold nanoparticles exhibit shape-dependent optical properties beneficial for optical sensing, biomedical imaging, and photocatalysis. This talk will discuss the fundamentals and applications of bio-compatible gold nanostars (AuNS) that support positive, negative, and neutral curvature. First, we will describe the details of AuNS growth and mechanistic insight gained from unconventional analytical tools. Second, we will discuss the functionalization with biological ligands that can facilitate both nanoparticle assembly and single-particle imaging of live-cell interactions. Finally, we will show how targeting nanoconstructs based on AuNS show distinct translational dynamics compared to their spherical counterparts when interacting with cancer cells.
