摘要

通过共沉淀法合成了右旋糖酐基质中的掺镁羟基磷灰石纳米颗粒（7MgHApDx），其平均粒径为 18.2 ± 0.5 nm。通过扫描电子显微镜（SEM）确定了 7MgHApDx 颗粒的表面形态和形状。通过超声波测量和 ZETA 电位对稳定性进行了评估，结果表明其具有良好的稳定性。此外，还通过傅里叶变换红外光谱研究确定了所研究样品中存在的官能团。测定了 7MgHApDx 悬浮液对金黄色葡萄球菌 ATCC 25923、大肠杆菌 ATCC 25922 和白色念珠菌 ATCC 10231 微生物菌株的抗菌特性。

Physico-Chemical and Antimicrobial Features of Magnesium Doped Hydroxyapatite Nanoparticles in Polymer Matrix

Magnesium doped hydroxyapatite nanoparticles in dextran matrix (7MgHApDx) with average size diameter of 18.2 ± 0.5 nm are synthesized by co-precipitation. The surface morphology and shape of 7MgHApDx particles are established by scanning electron microscopy (SEM). The stability that is evaluated by ultrasound measurements and zeta potential reveals a good stability. More than that, the functional groups present in the studied samples are identified by Fourier transform infrared spectroscopy studies. The antimicrobial properties of 7MgHApDx suspensions are determined against Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, and Candida albicans ATCC 10231 microbial strains.
