Hydrogels are a particular class of materials
based on three-dimensional networks made out of
polymers, able to absorb large quantities of
water.8
Their capacity to respond to external
stimuli like pH changes, chemical changes,
thermal and magnetic stimuli has drawn the
attention of the researchers.9
In the biomaterials
domain, the hydrogels are used as carriers for
active ingredients,10 as wound dressing and skin
grafts11 or as rheological modifiers
