摘要

纳米材料以其独特的性能和应用受到了科学界的广泛关注。小尺寸的金属氧化物为深入研究将其特性用于生物医学应用打开了大门。以聚乙烯醇(PVA)为燃料，采用固态燃烧法制备了银纳米粒子(AgNPs)和MgO、ZnO、NiO等金属氧化物纳米材料及其银掺杂纳米复合材料(Ag-MgO、Ag-ZnO、Ag-NiO)。采用x射线衍射仪(XRD)、扫描电子显微镜(SEM)和透射电子显微镜(tem)对所制备的氧化物及其掺杂银纳米复合材料的结构进行了表征。EDX图证实了金属在氧化物及其Ag复合材料中的存在。利用傅里叶变换红外(FT-IR)工具研究了复合材料的键合性质。研究了纳米复合材料对多种细菌的抑菌活性。

Solid state synthesis, characterization and biological evaluation of silver doped nanosized metal oxides

Nanomaterials have attracted a great deal of attention from the scientific community due to their unique properties and applications. The small size metal oxides have opened up the door for intensive research to utilize their properties for biomedical applications. Silver nanoparticle (AgNPs) and metal oxide nanomaterials like MgO, ZnO, NiO and its silver doped nanocomposites (Ag-MgO, Ag-ZnO, Ag-NiO) have been prepared using solid state combustion method using polyvinyl alcohol (PVA) as a fuel. The structure of as prepared oxides and its silver doped nanocomposites were characterized using X-ray diffraction (XRD) tool and morphology by Scanning Electron Micrograph (SEM) tool as well as Transmission electron micrograph tool respectively. Presence of the metals in the oxides and its Ag composite was confirmed by the EDX pattern. Bonding nature in the composite is well studied by the Fourier transform infrared (FT-IR) tool. Antibacterial activity studies of the nanocomposites are carried out against various bacteria.
