Nanoparticle synthesis and characterization overview of the AuNS seeds, AuNSs, AuNSTs and AuNFs.

Notes: (A) AuNS seeds: TEM image of AuNS seeds 15.2±1.2 nm, UV–VIS spectrum with a maximum at 520 nm and a size distribution histogram over 30 measurements. (B) AuNSs: TEM image of AuNSs 33.3±3.8 nm, UV–VIS spectrum with a maximum at 525 nm and a size distribution histogram over 30 measurements. (C) AuNSTs: TEM image of AuNSTs 26.0±2.6 nm, UV–VIS spectrum with a maximum at 630 nm and shoulder at 530 nm and a size distribution histogram over 30 measurements. (D) AuNFs: TEM image of AuNFs 40.6±2.2 nm, UV–VIS spectrum with a maximum at 563 nm and a size distribution histogram over 30 measurements (excluding the small spheres).

Abbreviations: AuNS, gold nanosphere; TEM, transmission electron microscopy; UV, ultraviolet; VIS, visible; AuNST, gold nanostar; AuNF, gold nanoflower; au, arbitrary unit.
