  1. Water-dispersed gold nanoparticles were produced by wet chemical reaction based on the reduction of tetrachloroauric acid. This technique allowed the synthesis of nanoparticles with increasing diameter, as shown by DLS and STEM.
  2. PDI: polydispersity index
  3. dV: mean diameter calculated by dynamic light scattering (DLS)
  4. D STEM: scanning transmission electron micrographs
