Material properties of 50∶50 CPTEG:CPH nanoparticles.

<p>Representative scanning electron photomicrographs of (<b>A</b>) blank and (<b>B</b>) 2% F1-V loaded 50∶50 CPTEG:CPH nanoparticles (scale bar = 1 µm). (<b>C</b>) Particle size distribution as determined by QELS for blank (204±62) and 2% F1-V loaded 50∶50 CPTEG:CPH nanoparticles (196±77) with n = 3. (<b>D</b>) <i>In vitro</i> cumulative release of F1-V from 50∶50 CPTEG:CPH nanoparticles in pH 7.4 PBS analyzed by micro bicinchoninic acid assay (n = 2, representative of two separate nanoparticle batches).
