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: This article refers to the development of a new environmentally friendly construction material; it mentions concepts of contamination in Colombia where the lack of reuse of recyclable materials is demonstrated with figures, and states its objectives and justification according to the needs or deficiencies outlined in the document. In the research, studies of similar models are carried out where research related to the proposed topic is shown; likewise, articles and national and international laws that support this work are evoked.

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
