A novel perfluorooctyl bromide (PFOB)-loaded nanovesicle with a size of about 500 nm was prepared by self-assembly of an amphiphilic block copolymer, poly(ethylene oxide)-b-poly(d,l-lactic acid) (PEG-PDLLA), for blood pool ultrasound imaging.

AbstractPoly(ethylene oxide)-b-poly(2-hydroxyethyl methacrylate) (PEO-b- PHEMA) was synthesized by successive atom transfer radical polymerization (ATRP) of 2-hydroxyethyl methacrylate（HEMA） monomer using PEO-Br macroinitiator as initiator, CuBr/CuBr2 and 2,2‟-bipyridyl (bpy) as catalyst and ligand. IR, 1H NMR, and GPC analysis indicate that PEO-b-PHEMA block copolymer with low polydispersity index (Mw/Mn≈ 1.1) has been formed. Selfassembly of this double hydrophilic block copolymer in the selective solvent and water was also studied. Owing to the high hydrophilic nature of the PEO and PHEMA blocks, this double hydrophilic block copolymer cannot disperse well in water. So block copolymer was modified by part esterification of PEO-b-PHEMA with acetic anhydride, which increased the hydrophobic group of the PHEMA block. The TEM results show that this block copolymer spontaneously form well-defined micelles in water.
