Abstract

During the past decades, HYDROGELS have been introduced suitable as novel materials for a variety of applications such as biomedical engineering, sanitary products, agriculture, bioseparation, enhanced oil recovery, etc. They have been successfully used as superabsorbent materials and in DRUG DELIVERY, cell encapsulation and tissue repair due to their high water content and consequent biocompatibility. Considering the fact that water retention in the HYDROGELS provides a suitable drug diffusion pathway; many hydrogel-based networks have been designed and fabricated as intelligent carriers of drugs. The rate and degree of hydrogel SWELLING are the most important parameters which control the release patterns of solvents and drugs from these polymeric networks. Therefore, the precise account of hydrogel behaviour as well as mathematical description of equilibrium SWELLING, dimensional changes due to solvent uptake, desorption and drug release profiles were the main objectives in many investigations. The objective of this manuscript is to give a brief review on existing mathematical models and theories in the field of hydrogel SWELLING as well as the description of the drug release mechanism from SWELLING-controlled networks. The most important properties of HYDROGELS relevant to their SWELLING behaviour as well as KINETICS and thermodynamic of SWELLING are also presented.
