Characterizations of the aliphatic HBPH polymer 4 and HBPH nanoparticles (HBPH NPs). A) Gel Permeation Chromatographic (GPC) trace of the polymer 4, showing the formation of high molecular weight polymer. B) Determination of the hydrodynamic diameter of the as-synthesized HBPH nanoparticles (Cyt C-HBPH NPs) using Dynamic Light Scattering (DLS: D = 63±2 nm, PDI = 0.73). C) Comparison between the UV/Vis absorption spectrum of Cyt C encapsulating nanoparticles (Cyt C-HBPH NPs) with that of free Cyt C and HBPH nanoparticles (HBPH NPs) itself, in solution. D) UV/Vis absorbance spectra of folate functionalized DiI and Cyt C encapsulating HBPH nanoparticles.
