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

Table 1

Changes in particle size distribution after dispersion of nanoemulsions in media simulating physiological conditions. Control, empty (NE), and plumbagin-loaded (NE-PL) nanoemulsions (3.5% polysorbate 80) were dispersed in indicated media (1000 x dilution) and incubated for 24 h at 37°C. The particle size distribution was determined by DLS. PDI values are indicated in brackets.
