Paper Title
Self-Healing Injectable Hydrogel With Magnetic Microcapsule On The Evaluation Of Cartilage Repair

Abstract
In this study, themagnetic guiding carrier based on Fe3O4 nanoparticles and self-healing hyaluronan hydrogel has demonstratedmagnetic guiding characteristic and chemical properties. The magnetic microcapsules- HA-AGMCs incorporating with Fe3O4 nanoparticles were successfully synthesized by double emulsification.Incorporating with magnetic nanoparticles,the HA-AGMCs can be guided to specific injured sites.The host polymer(HA-CD) and guest polymer(HA-Fc) was synthesized successfully. The combination of magnetic microcapsules and self-healable hydrogel is expected to provide more effective treatment in osteoarthritis.
