Figure 2

TEM images of non-irradiated particles, (a) AuNPs and (c) AuPEG2000-NH2, in comparison with irradiated products, (b) iAuNPs and (d) iAuPEG2000-NH2. The polymer coating has a slight influence on the particle size, but showing a more significant effect on aggregation behavior. The irradiated PEGylated nanoparticles exhibit a phenomenon of uniform clustering, with the formation of entities with dimensions up to 100 nm. The histograms indicating dimensional distribution by measuring about 1000 particles from several TEM images, of which only representative ones are illustrated above.
