Abstract: | Self-healing hydrogel is a new generation smart material that has drawn great attention among researchers from multiple cutting edge areas.Self-healing hydrogels are continuously enriching our knowledge in developing new materials and changing our lives.In the recent decades,thanks to numerous dedicated researchers,series of self-healing hydrogels have been explored through dynamic chemistry and supramolecular interactions,which have been applied in interdisciplinary areas for controlled release of drugs,3 D cell culture,and scaffolds of tissue engineering,etc.Self-healing hydrogels can be injected as solid gels instead of liquid precursor,then selfheal in situ.Thus,self-healing hydrogels have been utilized as a new type of injectable carrier to deliver drugs.This method effectively avoids unwanted cargo loss throughout the cycling and dramatically improves the delivery efficiency of drugs.Thus,self-healing hydrogels have been studied in recent research as great therapeutic carrier for tumour therapy and wound-healing.This review aims to summarize some recent research progresses in the preparation of self-healing hydrogels based on different dynamic covalent bonds.The bio-medical applications of self-healing hydrogels including tumour therapy and wound-healing have also been introduced.The future development and challenges of dynamic chemistry based on self-healing hydrogels have also been discussed. |
