A novel degradable polymeric carrier for selective release and imaging of magnetic nanoparticles

Chem Commun (Camb). 2010 Sep 28;46(36):6708-10. doi: 10.1039/c0cc01857k. Epub 2010 Aug 16.

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.
