23 Jul Selenium-doped biphase calcium phosphate composite nanometer particle, selenium-doped biphase calcium phosphate composite silver nanometer particle and preparation methods of selenium-doped biphase calcium phosphate composite nanometer particle and selenium-doped biphase calcium phosphate composite silver nanometer particle
Abstract
The invention discloses a selenium-doped biphase calcium phosphate composite nanometer particle which is prepared through a vacuum drying method. With biphase calcium phosphate being a matrix, duringstirring, a crosslinking reaction occurs, selenite radicals replace part of phosphate radicals in biphase calcium phosphate, and through a silver fall reaction, silver ions replace part of hydrogen ions; the prepared selenium-doped biphase calcium phosphate composite nanometer particle and a prepared selenium-doped biphase calcium phosphate composite silver nanometer particle can be used for inorganic material parts of bone tissue engineering to improve the anti-bacterial performance of the materials, the two kinds of materials have the good anti-bacterial performance and cell compatibility and are free of toxic and harmful effects on living bodies, raw materials are convenient and easy to obtain, preparation methods are simple and convenient, operability is high, and application and popularization are convenient.
