(A) Experimental dark-field scattering microscopy images of 80 nm diameter AuNSs in dielectric medium; and (B) PEG AuNPs embedded in HeLa cells. Distinct color circles represent monomer (P18) and cluster (P14 and P15), and intensity variation is due to various separations. (C) Confocal laser scattering images of PEG AuNPs HeLa cell sample, attached with dye molecules. The red spherical borders are cell membranes, and small colorful spherical particles (eg, red, yellow and green, etc.) are AuNPs.

Abbreviations: AuNSs, gold nano-spheres; PEG, pegylated; AuNPs, gold nanoparticles; P, particle.
