Analysis of complexes formed by small gold nanoparticles in low concentration in cell culture media

Fig 1

Dynamic light scattering of 20 nm gold nanoparticles in protein poor (expansion) and protein rich (RPMI) cell culture media.

a) shows intensity size distribution of 20 nm Au NPs in water (black line), after 30 minutes (light orange), 1 hour (medium orange), and 24 hours (dark orange). b) shows the intensity size distribution of the RPMI media without NPs (light blue), and the size distribution after 30 minutes (light orange), and 24 hours (dark orange). c) shows the intensity autocorrelation as a function of time for the size distribution presented in a), and d) shows the intensity autocorrelation for the size distribution presented in b).
