A. Particle size analysis of ICG-loaded mixed micelles in PBS as a function of micelle composition (PEO-PHB-PEO to PF-127 ratio). Increasing the fraction of PF-127 at 37 °C decreases micelle effective diameter. Stable micelles are not formed with pure PF-127 at RT (ND = not determined). B. Polydispersity of ICG-loaded micelles in PBS at 37 °C.
