Plumbagin-Loaded Nanoemulsion Drug Delivery Formulation and Evaluation of Antiproliferative Effect on Prostate Cancer Cells

Figure 3

Time-dependent intensity-based particle size distribution profiles of plumbagin-loaded microemulsions at different surfactant concentrations (S%, w/w). A: particle size is indicated as Z-average hydrodynamic diameter (nm) determined by cumulants fit analysis from DLS measurements. B: heterogeneity of size distribution is indicated by polydispersity index (PDI).
