A drug delivery system (DDS) can be defined as a formulation or a device that facilitates the release of a therapeutic substance in the body. Key parameters of interest in DDS are safety, delivery rate, efficiency, as well as time and place of release of drugs. Lately, hydrogels have attracted significant attention for application in drug delivery. Hydrogels are three-dimensional polymer networks consisting largely of water. They are characterised by a porous structure with porosity, pore size and geometry that can be varied during the hydrogel synthesis. Importantly, due to porous structure they have the ability to incorporate biomolecules.
