Figure 5. Zeta potential values obtained for mucin and FITC-loaded CS/TCS-SA NPs before and after incubation with mucin. The influence of mucin on the zeta potential of NPs revealed a reduction, and The gap in TCS-SA NPs was larger than in CS-SA NPs. Experiments were performed in triplicates (***p<0.0001).
