  1. Table of cell viabilities (expressed as % of non-irradiated treatment control for a given concentration of nanoconjugates, after adjustment for baseline cytotoxicity) for SK-N-AS and SK-N-DZ cells treated with varying concentrations of bare nanocomposites and different doses of ionizing radiation (Fig. 5). Entries contain mean ± SD. **: < 0.01 significance level, *** < 0.001 significance level.
