Exploring polyethylene glycol/cyclodextrin hydrogels with spin probes and EPR spectroscopy.
Formation of organogels from covalently linked polyethylene glycols and cyclodextrins and their encapsulation/release properties were monitored with EPR spectroscopy using spin labels and spin probes; changes in molecular tumbling rates provided information on spin probe/label location inside the gel network, and molecular properties of the gel.
