Nanoparticle characterization schematic. (A) UV-vis spectra of res, Pluronic F127, Vitamin E TPGS, Res-NP and Empty NP. Notes: Res shows a characteristic absorption peak at around 318 nm. Abbreviations: Res, resveratrol; Res-NP, Resveratrol loaded nanoparticle; and Empty-NP, empty nanoparticle. (B) Particle size distribution obtained from TRPS analysis of res-loaded nanoparticles. Solid lines: Gaussian distribution fits of two nanoparticle populations detected (red and green) and cumulative particle size distribution (black). Abbreviations: Res-NP, Resveratrol loaded nanoparticle. (C) Scanning electron microscopy (SEM) images of res-loaded NPs. The scale bar is 1 µm and the magnification during imaging was 120,000×. A and B are two indicative particles with sizes of 140 nm and 179 nm, respectively.
