Table 1. Summary of DLS Hydrodynamic Diameters (Dh), Initial and Final Silica Contents Determined by Thermogravimetry (TGA) Before and After Centrifugation, TGA-Derived Silica Loading Efficiency (LETGA), Effective Density (ρeff), Number of Silica Nanoparticles Per Vesicle (Nsv), and Encapsulation Efficiency (EEDCP) Determined Using Disk Centrifuge Photosedimentometry (DCP), SAXS-Derived Vesicle Diameter (where Dv = 2Rv and σDv Is Its Standard Deviation), and the Concentration of Encapsulated Silica Obtained for a Series of G58H250 Diblock Copolymers Prepared in the Presence of 0–35% w/w Silica.
