Figure 5: The uptake of different zeta potential and size docosanoic acid SLNs entrapped enrofloxacin in RAW.264.7 cells.

The SLNs with 7.1 mv and 501 nm were prepared with 0.2 g enrofloxacin, 1.8 g docosanoic acid, and 20 ml 2% PVA and 3% DDAC. The SLNs with 18.8 mv and 345 nm were prepared with 0.2 g enrofloxacin, 1.8 g docosanoic acid, and 20 ml 2% PVA and 4% DDAC. aStatistical significances compared with 7.1 mv are p < 0.05.
