Abstract: Photothermal therapy (PTT) is an alternative new cancer treatment after surgery, radiotherapy and chemotherapy. Thinking about the characteristics of tumor photothermal therapy, the key factors of photothermal nanomaterials in clinical applications include theire photothermal conversion efficiency, surface modification activity, biocompatibility, biodegradability and low toxicity. With the development of photothermal nanomaterials, PTT holds immense potential in clinical translation. Up to now, four generation of photothermal nanomaterials have been developed, including noble metal nanoparticles, carbon based nanomaterials, metal and non-metallic compound nanomaterials and organic dyes.

Abstract : It is low feasibility using plasma energy particles to excite, ionize and break bonds molecules on the surface of aliphatic polyester biomaterials to produce new topological structures. The biomimetic phosphatidylcholine modification technology of aliphatic polyester biomaterials was studied. The phosphatidylcholine monomer [2 (methacryloxy) ethyl]phosphatidylcholine was synthesized by reaction of 2 chloro 1, 3, 2 dioxaphosphoric heterocyclic pentane with different raw material solutions; the phosphatidylcholine[2 (methacryloxy) ethyl]phosphatidylcholine, acrylonitrile and water were copolymerized to form PANCMPC; the phosphatidylcholine [2 (methacryloxy) ethyl]phosphatidylcholine was replaced by PANCMPC, and PANCHEMA was obtained by repeated copolymerization. PANCHEMA was reacted with 2 chloro 2 oxygen 1, 3, 2 dioxophosphorus heterocyclic pentane, and then opened with trimethylamine to form biomimetic phospholipid modified PLCANCP. Experiments show that the proposed technology has good hydrophilicit
