摘要

采用微弧氧化（MAO）法制备了Fe-Cu纳米颗粒改性磷酸钙（CaP）涂层。主要研究了涂层的形态、元素组成、相组成、表面电荷性质以及抗菌活性和细胞毒性。结果表明，Fe-Cu纳米粒子的加入通过减少金黄色葡萄球菌的活菌数量来提高涂层的抗菌性能，并提高涂层的生物相容性。这使得涂层有望用于医疗植入物，提供必要的成分和孔隙度以及改进的生物特性。

Fe–Cu nanoparticle-modified calcium phosphate coatings: enhanced antimicrobial and biocompatibility properties

Calcium phosphate (CaP) coatings modified with Fe–Cu nanoparticles have been manufactured using the micro-arc oxidation (MAO) method. The primary focus was on the morphology, elemental composition, phase composition, and surface charge properties as well as the antimicrobial activity and cytotoxicity of the coatings. It is demonstrated that the addition of the Fe–Cu nanoparticles enhances the antimicrobial properties of the coatings by reducing the number of viable Staphylococcus aureus bacteria and increases the biocompatibility of the coatings. This makes the coatings promising for use in medical implants, providing the necessary composition and porosity along with the improved biological characteristics.
