Amphiphilic block copolymer based on poly(ethylene glycol) methyl ether methacrylate (POEGMEMA) and a block with pendant cyclodextrin units were self-assembled into micelles in the presence of the hydrophobic bile acid-based Pt(IV) drug, which also acted as crosslinker.

This work presented the surface modification of magnetite nanoparticle (MNP) with poly[(t-butyl acrylate)-stat-(poly(ethylene glycol) methyl ether methacrylate)] copolymers (P[(t-BA)-stat-PEGMA])viaa surface-initiated “grafting from” atom transfer radical polymerization (ATRP). Loading molar ratio oft-BA to PEGMA was systematically varied (100 : 0, 75 : 25, 50 : 50, and 25 : 75, resp.) such that the degree of hydrophilicity of the copolymers, affecting the particle dispersibility in water, can be fine-tuned. The reaction progress in each step of the synthesis was monitoredviaFourier transform infrared spectroscopy (FTIR). The studies in the reaction kinetics indicated that PEGMA had higher reactivity than that oft-BA in the copolymerizations. Gel permeation chromatography (GPC) indicated that the molecular weights of the copolymers increased with the increase of the monomer conversion. Transmission electron microscopy (TEM) revealed that the particles were spherical with averaged size of 8.1 nm in diameter. Dispersibility of the particles in water was apparently improved when the copolymers were coated as compared to P(t-BA) homopolymer coating. The percentages of MNP and the copolymer in the composites were determinedviathermogravimetric analysis (TGA) and their magnetic properties were investigatedviavibrating sample magnetometry (VSM).
