MGSO-3 cell viability determined by an MTT assay for Lip and Lip-Fe3O4@lecithin. Mean cell viability was normalized by the mean viability of the control group. Error bars denote ± SD. Stars indicate statistical significance at the p ≤ 0.05 (*) level as determined by one-way ANOVA, followed by a Tukey’s post-test. The experiments were performed in biological triplicates (n = 3).
