Characterization of AuNPs.

Notes: (A) UV-visible spectrum showed an absorption peak at 520 nm. (B) The hydrodynamic size distribution was 34.09±2.4 nm, as measured by DLS. (C) FETEM images of AuNPs (bar: 200 nm). (D) FETEM images of AuNPs (bar: 20 nm). (E) The zeta potential was −31.7±1.7 mV, as measured by DLS.

Abbreviations: AuNPs, gold nanoparticles; UV, ultraviolet; DLS, dynamic light scattering; FETEM, field emission transmission electron microscopy; OD, optical density.
