Figure 3.
Scanning electron microscopy (SEM) showing the behavior of hNSCs and MTS assay for biocompatibility and long term survival of differentiated hNSCs on GO and SiNP-GO. a) SEM images confirm that the axons do not align on control and SiNP substrates and they align on GO and SiNP-GO substrates. Scale bar is 10 μ m. b) MTS assay results show that GO and SiNP-GO is biocompatible and aids in the long term survival of hNSCs as compared to glass and SiNPs. The results have been normalized to hNSC viability on GO.
