Environmentally Friendly Synthesis of Hydroxyapatite Nanoplates and their Adsorption Behavior of Proteins

摘要

By a environmentally friendly method with the control of anionic amino acid surfactant N-lauroylsarcosine sodium (Sar-Na),hydroxyapatite (HAP) nanoplates were synthesized and the adsorption behavior of bovine serum albumin (BSA) were carefully studied.The products were characterized by transmission electron microscopy (TEM),X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR).Results showed that hydroxyapatite nanocrystals with lengths of 100 nm,a width of 10 nm and a high aspect ratio (10:1) were obtained.Results of UV-Vis spectrum indicate that prepared hydroxyapatite nanoplates can be effectively adsorbed BSA.The current work provides a new approach to produce biomaterials.
