Physical characterization of the nanostructures.

Notes: (A) UV–vis absorption spectra of gold nanoparticles (black spectrum) and Tween^® 20-coated GNPs (red spectrum). The spectra are normalized to unity for better illustration. Inset: TEM image of gold nanoparticles. (B) Shows assigned values of nanoparticle hydrodynamic diameter determined by DLS, zeta potential, diameter determined by TEM, and LSPR band position. “–” indicates no data.

Abbreviations: GNPs, gold nanoparticles; TEM, transmission electron microscopy; DLS, dynamic light scattering; LSPR, localized surface plasmon resonance; au, arbitrary units; UV, ultra violet.
