Figure 4: PNT1A cell proliferation after treatment with bare and pegylated PHAuNPs for 24 and 72 hours. All the values depicted have been normalized to the non treated control (0 µM). After 72 hours of treatment, there was a significant decrease in the proliferation of cells treated with 100 μM bare nanoparticles. The horizontal bars indicate that there is a significant difference at %.
