Figure 3: Cellular viability of NIH-3T3 of mesoporous silica and OMV. In (a) it view the OMV, SBa-15 and SBa-16 in several concentration in neutral red uptake assay for cellular viability verification. In (b) it observed the comparation of OMV and mesoporous silica association at different concentrations. All the neutral red assay non show a cytotoxicity effect in NIH-3T3 cells line.
