- ... Methods are presented for creating biocompatible composites with magnetic functionality by incorporating magnetic nanoparticles in a biodegradable polymer matrix. A wide range of volume fractions for magnetic particle loading and therefore magnetization density are achievable. The nanoscale of the particles aids in achieving dispersion, so that variations in physical and chemical properties occur ...

- ... A novel biodegradable amphiphilic copolymer with hydrophobic poly(ε-caprolactone) branches containing cholic acid moiety and a hydrophilic poly(ethylene glycol) chain was synthesized. The copolymer was characterized by FTIR, ¹H NMR, gel permeation chromatography (GPC), differential scanning calorimetry (DSC), polarizing light microscopy (PLM), and wide-angle X-ray diffraction (WAXD) analysis. The ...
