 (2) Title: 

Magnetoelectric Coupling Biomimetic Hydrogel for Cartilage Repair

 (3) Research idea: 

This work designs a sodium alginate-based double-network biomimetic hydrogel system incorporated with piezoelectric components and magnetostrictive nanoparticles to mimic the physicochemical and mechanical features of native cartilage. Joint movement triggers magnetoelectric coupling conversion to generate endogenous electromagnetic stimulation for regulating the biological behaviors of chondrocytes.

 (4) Material development: 

1) Materials: sodium alginate, polyhydroxybutyrate-valerate, Fe₃O₄ nanoparticles;

(2) Functions: generate magnetoelectric coupling stimulation in response to movement, regulate chondrocyte differentiation, suppress inflammation, and facilitate the repair of cartilage defects.

We provide full-process services for custom material design, including innovative scheme design, fabrication, characterization, and in vitro & in vivo validation (cell and animal studies). Our postdoctoral team with multiple high-impact Q1 publications can tackle your challenging research demands. Our scope covers hydrogels, drug delivery systems, nanomaterials, polymers, liposomes, microneedles and more.
