Abstract

The invention discloses a conductive hydrogel scaffold material, a preparation method and an application thereof for synergistically treating osteosarcoma and promoting bone regeneration. The scaffold material comprises: GelMA / Ode hydrogel, PVP‑PPy conductive polymer, mechanical performance enhancement Particles, and bone growth-promoting elements; wherein, according to the mass ratio GelMA / Ode hydrogel: PVP-PPy conductive polymer: mechanical performance enhancing particles: bone growth-promoting elements=(11~40):(0.01~1):( 0.5~2): (0.5~3). In the present invention, GelMA / Ode hydrogel, MMT-Sr particles, and PVP-PPy conductive polymer are polymerized, GelMA / Ode hydrogel can load drugs, PVP-PPy conductive polymer has excellent photothermal conversion performance, and the material can As a preparation material for promoting bone tissue regeneration scaffold.

Description

technical field [0001] The invention relates to the field of biomaterials, in particular to a conductive hydrogel scaffold material for treating osteosarcoma and promoting bone regeneration, a preparation method and an application thereof. Background technique [0002] Osteosarcoma is the most common primary malignant bone tumor and is a common type of cancer in children and adolescents. Osteosarcoma is a malignant neoplasm of mesenchymal origin, in which malignant spindle-shaped stromal cells produce osteoid tissue. Surgery can directly remove the tumor, but it cannot avoid the recurrence or bone defect caused by osteosarcoma. The rise of combined surgery and chemotherapy has reduced the risk of recurrence in patients with osteosarcoma to some extent. Chemotherapy has long been the standard treatment for osteosarcoma. However, the rapid metabolism of small molecule drugs, side effects of chemotherapy, such as allergies, gastrointestinal toxicity, lead to poor therapeutic...
