Cytotoxicity of GNPs determined by the MTT test. (a) Viability of HeLa (first two blocks) and BHK-21 cells after 48 h of incubation with different GNPs. Concentrations of GNPs are given under the horizontal axis. The vertical axis represents the percentage of viable cells. The viability of untreated cells was set as 100%. (b) Mitosis in the BHK-21 culture treated with PEI-GNRs. Arrows show chromosomes and boxes indicate PEI-GNRs in lysosomes. The inset shows an enlarged fragment of a lysosome filled with PEI-GNRs. TEM of ultrathin sections.
