Hydrogels are made of interconnecting chains of natural or synthetic polymers joined by cross-linkers to create a hydrophilic substance with the macromolecular structure of a gel. They have the capacity to grow many times their dry weight and may include as much as 99 percent water or biological fluids. These three-dimensional (3D) highly hydrated porous networks are usually made to store, release, or collect materials and can replicate the natural tissue microenvironment.

摘要

Hydrogels are made of interconnecting chains of natural or synthetic polymers joined by cross-linkers to create a hydrophilic substance with the macromolecular structure of a gel. They have the capacity to grow many times their dry weight and may include as much as 99 percent water or biological fluids. These three-dimensional (3D) highly hydrated porous networks are usually made to store, release, or collect materials and can replicate the natural tissue microenvironment.
