The morphological characteristics and particle size of the vincristine nanoparticles\u0000were examined. The surface charge and average dynamic size, encapsulation efficiency in\u0000addition to release profile study were also evaluated.\u0000\u0000\u0000\u0000Dynamic Light Scattering confirmed the small size of nanoparticles (~200 nm). SEM showed\u0000spherical-shaped nanoparticles with smooth surfaces, and the polydispersity index values of the prepared\u0000nanoparticles were below 0.5 in all preparations. The zeta potential of the nanoparticles was\u0000found to be negative, which can be attributed to the presence of carboxylic groups in the PCL polymer,\u0000The encapsulation efficiency of Vincristine-loaded nanoparticles (NPs) varied from 36% to 57% for all\u0000the prepared NPs with varying amounts of PCL.
