Water swollen polymer networks, generally referred to as
hydrogels, have received a great deal of attention for a wide variety
of biomedical applications such as tissue engineering, cell encapsulation,
wound dressing and drug delivery [1]. The hydrophilic
polymer network of hydrogels allows a high water content similar
to natural tissues. Their swelling properties, as well as their
biocompatibility, makes hydrogels ideal candidate materials for the
repair and regeneration of soft tissues.
