Research advances of applying intelligent hydrogels in the field of biomedicine
As a polymer material with a three-dimensional network structure,hydrogel has excellent properties of hydrophilic-ity,flexibility and swelling.Also it has decent biocompatibility and degradability.Therefore hydrogels have great potential appli-cations in such biomedical fields as drug delivery and tissue scaffolds.Summarizing the latest domestic and foreign literatures,this review introduced different types of hydrogels responsive to temperature,pH,redox,enzyme,electricity and multiple factors.The applications of hydrogels in biomedicine included tissue engineering,drug carrier,dressing,sensor and 3D cell culture.
