a crosslinked polymeric system that can absorb and retain water in an equilibrium state
a gel-like material having an affinity for water and similar compounds
a highly-interdependent, biphasic matrix consisting of a solid component (usually a polymer, and more commonly a highly cross-linked polymer) that has both hydrophilic and hydrophobic character
a hydrated crosslinked or insolubilized polymeric system that contains water in an equilibrium state
a hydrated cross-linked polymeric system that contains water in an equilibrium state
a polymer network swollen with large amount of water
A coated material consisting of mostly water used for delivery of medications transdermally, to provide lubricious coatings to medical devices, and promote wound care. These gels can be used in wound care applications, or loaded with a variety of topical skin care products.
Polymer capable of absorbing high proportions of water without passing into solution.
polymer network in which a liquid (water) has been absorbed; also known as hydrophilic plastic.
A colloidal gel in which the particles are dispersed in water.
Hydrogel is a network of polymer chains that are water-soluble, sometimes found as a colloidal gel in which water is the dispersion medium. Hydrogels are superabsorbent (they can contain over 99% water) natural or synthetic polymers. Hydrogels possess also a degree of flexibility very similar to natural tissue, due to their significant water content.
