Spin Probe Method for Diagnostics of Polyster Porous Matrixes Formed in Supercritical Carbon Dioxide

The review is devoted to the electron paramagnetic resonance (EPR) studies of porous polymer materials (matrixes) obtained from aliphatic polyesters and doped with paramagnetic biologically active substances by means of supercritical fluid technologies. Particular attention is paid to the possibilities of the EPR-spectroscopy for establishing the regularities of the formation of the matrixes, the subsequent characterization of the materials obtained, and also the features of the dopant release to aqueous solutions in vitro.

Key words: porous polymeric materials, alifatic polyesters, nitroxide radicals, electron paramagnetic resonance
