Nano-catalytic materials have broad application prospects in solving bacterial resistance caused by overuse of antibiotics. However, their catalytic efficiency usually depends on a lower pH value range (i.e., pH=2.0-5.0) rather than on a weakly acidic bacterial microenvironment (i.e., pH=6.0-7.0), leading to an limited catalytic efficiency and an insignificant bactericidal effect. In this paper, MnSiO3 samples were prepared by a simple co-precipitation method. The morphology, structure and catalytic properties of the samples were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM) and ultraviolet-visible spectroscopy (UV-Vis). The antibacterial performance against E. coli and S. aureus were investigated. The results show that the morphology of amorphous MnSiO3 samples transforms from nano-sized particles to micron-sized blobs in buffer solutions at pH 6.4 and 7.0. MnSiO3 nano-sized particles had an intense catalytic ability at a higher pH value and an excellent antibacterial performance against E. coli and S. aureus. Therefore, the in-situ structure transformation of MnSiO3 presents a promising treatment strategy for bacterial infection.

纳米催化抑菌材料在解决因抗生素滥用导致的细菌耐药性方面具有广阔的应用前景,但其催化效率受限于低的pH值环境(pH=2.0~5.0),而实际的细菌微环境pH值相对较高(pH=6.0~7.0),这导致大多数材料催化效率有限、杀菌效果不理想。本研究用简单的共沉淀法一步制备了MnSiO3纳米颗粒,采用透射电子显微镜(TEM)、扫描电子显微镜(SEM)、紫外可见光谱(UV-Vis)等测试手段对样品的形貌、结构和催化性能进行了表征,研究了其对大肠杆菌和金黄色葡萄球菌的抑菌性能。结果表明:非晶态的MnSiO3纳米颗粒在pH值为6.4、7.0的缓冲溶液中,形态从纳米颗粒转变成微米花球;MnSiO3纳米颗粒在较高pH值下具有强催化能力,对大肠杆菌和金黄色葡萄球菌表现出了优异的抑菌性能。因此,可原位形貌转变的MnSiO3材料在抗菌感染的治疗方面具有一定的应用优势。

纳米催化抑菌材料在解决因抗生素滥用导致的细菌耐药性方面具有广阔的应用前景,但其催化效率受限于低的pH值环境(pH=2.0~5.0),而实际的细菌微环境pH值相对较高(pH=6.0~7.0),这导致大多数材料催化效率有限、杀菌效果不理想。本研究用简单的共沉淀法一步制备了MnSiO3纳米颗粒,采用透射电子显微镜(TEM)、扫描电子显微镜(SEM)、紫外可见光谱(UV-Vis)等测试手段对样品的形貌、结构和催化性能进行了表征,研究了其对大肠杆菌和金黄色葡萄球菌的抑菌性能。结果表明:非晶态的MnSiO3纳米颗粒在pH值为6.4、7.0的缓冲溶液中,形态从纳米颗粒转变成微米花球;MnSiO3纳米颗粒在较高pH值下具有强催化能力,对大肠杆菌和金黄色葡萄球菌表现出了优异的抑菌性能。因此,可原位形貌转变的MnSiO3材料在抗菌感染的治疗方面具有一定的应用优势。

Nano-catalytic materials have broad application prospects in solving bacterial resistance caused by overuse of antibiotics. However, their catalytic efficiency usually depends on a lower pH value range (i.e., pH=2.0-5.0) rather than on a weakly acidic bacterial microenvironment (i.e., pH=6.0-7.0), leading to an limited catalytic efficiency and an insignificant bactericidal effect. In this paper, MnSiO3 samples were prepared by a simple co-precipitation method. The morphology, structure and catalytic properties of the samples were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM) and ultraviolet-visible spectroscopy (UV-Vis). The antibacterial performance against E. coli and S. aureus were investigated. The results show that the morphology of amorphous MnSiO3 samples transforms from nano-sized particles to micron-sized blobs in buffer solutions at pH 6.4 and 7.0. MnSiO3 nano-sized particles had an intense catalytic ability at a higher pH value and an excellent antibacterial performance against E. coli and S. aureus. Therefore, the in-situ structure transformation of MnSiO3 presents a promising treatment strategy for bacterial infection.
