title: A novel degradable polymeric carrier for selective release and imaging of magnetic nanoparticles.
abstract: A water-soluble, pH-responsive copolymer was synthesized successfully and used as a polymeric carrier to deliver hydrophobic paramagnetic nanoparticles into cells. In an acidic environment, the nanoparticles aggregate as the copolymer degrades, resulting in the enhancement of an in vitro MRI signal.
