ABSTRACT
Welcome to the guest zone: By combining hyperpolarized xenon and simple low-field NMR devices it is possible to obtain more control over hydrogels that show potential as drug delivery systems. An alternative way of polymer swelling-degree determination is demonstrated with real-time NMR analysis. An ideal region for solvent uptake can be defined in which the absorbed solvent molecules are completely confined in the nano-porous network of the hydrogel.
