Nano mesoporous and porous materials with special physical and chemical properties due to its special structure , this new material has aroused great interest of the majority of scientific research . 1992 success of mesoporous silica zeolite synthesis caused extensive study of the research staff of the special pore structure of mesoporous materials , to explore the synthesis of nano- and mesoporous materials and emerging applications will become the focus of the materials in the field . Hydroxyapatite as the main inorganic component of bone , has good bioactivity and biocompatibility , non-toxic side effects , it is widely used in hard tissue repair replacement carrier and . This thesis is a brief summary of the biological material and its classification , hydroxyapatite and other phosphate research on materials , and describes the immobilized enzymes and antibacterial research profile . Thesis work mainly consists of the following : (1) hydroxyapatite ceramic material preparation and properties of yeast cells as a template prepared nanosized mesoporous hydroxyapatite powder ( Chapter 2 ) of this thesis as the main raw material add a certain binder , obtained by tableting molding and preparation of different temperature calcined hydroxyapatite bulk material , study its corresponding various properties . (2 ) hydroxyapatite porous ceramic material containing enzyme performance study ( Chapter 3 ) the preparation of papers using traditional pottery , yeast templates prepared nanosized mesoporous hydroxyapatite powder as raw material , the preparation of porous hydroxyapatite apatite bulk material , and the performance of its contained enzymes were studied . (3) mesoporous phosphate immobilized enzyme inhibitory properties of ( Chapter 4 ) In this thesis the synthesis of a variety of biological template mesoporous phosphate materials immobilized containing enzymes and antibacterial experiments using iodine achromatic Law Determination of α-amylase activity , research and analysis phosphate immobilized enzyme inhibitory properties ( 4) of biological the template zinc phosphate calcium and zinc phosphate synthesis and Characterization ( Chapter 5 ) (5) of hydroxyapatite / alginate sodium ( Chapter 6 ) to study the biological template prepared by a variety of nano-phosphate performance and development of the green biomimetic synthesis of phosphate composites . Tested analysis found that the biological templates phosphate material has good adsorption , immobilized contained enzyme performance and antibacterial properties , these properties have broad application prospects in the field of environmental science, life science .
