Injectable Biomimetic Gels for Biomedical Applications

Injectable biomimetic gels are advancing biomedical applications by mimicking the extracellular matrix to support tissue regeneration, wound healing, and drug delivery. These hydrogels, made from materials like gelatin, chitosan, and hyaluronic acid, exhibit properties such as self-healing, mechanical flexibility, and biocompatibility. They have shown promise in promoting vascularization, bone regeneration, and cartilage formation, with specific examples including ECM-mimetic hydrogels and alginate bioconjugates. Despite their potential, challenges remain in enhancing mechanical resilience, degradation control, and targeted delivery. Future research aims to optimize these properties and integrate technologies like 3D bioprinting to fully realize their potential in regenerative medicine.
