Designing Gold Nanoparticle-Ensembles as Surface Enhanced Raman Scattering Tags inside Human Retinal Cells
Figure 6
MTT test of epithelial cells from human retina (D407 cells viability (%)) treated with various concentrations of PEG-GENs and GNPs. The effect of supernatant onto cell viability is also presented. Data are presented as means and standard errors of the mean (SEM): *significant , **very significant .
