 Self-healable hydrogels have been developed as a promising alternative to brittle hydrogels currently used in preclinical and clinical trials. However, these hydrogels still face challenges due to their lack of compatibility with hydrogel toughness and rapid self-healing. Additionally, they need to meet a variety of requirements such as electrical, biological and mechanical properties. Nanomaterials have shown great promise in developing multifunctional and self-healable hydrogels for various tissue engineering applications. These hydrogels have the potential to be used in bio-electronic hydrogels, cyborganics and soft robots. This article was authored by Saper-Tolibian, Medi-Mirali, Neyar-Otidnia and others.
