Abstract

The authors report the preparation of the nanocomposite comprising of vanadium pentoxide (V₂O₅) and selenium (Se) nanoparticles and functionalized multiwalled carbon nanotubes (MWCNTs) (V₂O₅@Se NPs/MWCNTs). Since Se NPs possesses extraordinary physicochemical properties including larger surface area with higher adsorption capacity, V₂O₅ NPs were adsorbed onto Se NPs surface through physisorption process (designated as V₂O₅@Se NPs). The nanocomposite synthesized hydrothermally was evaluated for its antimicrobial activity. The morphology and microstructure of the nanocomposite were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis, respectively. Fourier transform infrared spectroscopy (FTIR) and UV-Visible spectroscopy (UV-Vis) were employed to analyze the spectral properties of nanocomposite. The microbicidal efficacy of nanocomposite was tested against Gram-negative (G-)ZGram-positive (G+) bacteria and fungus. This is the first report on the synthesis of V₂O₅@Se NPs/MWCNTs nanocomposites by chemical method that showed microbicidal effect on micro-organisms. The thiol (-SH) units facilitates the enrichment of V₂O₅@Se NPs onto MWCNTs surface. Ultimately, it reflects on the significant antimicrobial activity of V₂O₅@Se NPs/MWCNTs.

V₂OO5©纳米硒纳米复合材料与多壁碳纳米管抗菌活性的合成

作者报道了由五氧化钒(V₂O5)和硒(Se)纳米粒子和功能化多壁碳纳米管(V₂O5@Se NPs/MWCNTs)组成的纳米复合材料的制备。由于Se NPs具有更大的表面积和更高的吸附容量等特殊的物理化学性质，因此通过物理吸附过程将V₂O5 NPs吸附在Se NPs表面(称为V₂O5@Se NPs)。对水热合成的纳米复合材料进行了抗菌活性评价。采用扫描电子显微镜(SEM)和x射线衍射仪(XRD)对纳米复合材料的形貌和微观结构进行了表征。采用傅里叶变换红外光谱(FTIR)和紫外可见光谱(UV-Vis)分析了纳米复合材料的光谱特性。研究了纳米复合材料对革兰氏阴性菌(G-)、革兰氏阳性菌(G+)和真菌的杀菌效果。本文首次报道了用化学方法合成对微生物具有杀微生物作用的V₂O5@Se NPs/MWCNTs纳米复合材料。巯基(-SH)单元促进了V₂O5@Se NPs在MWCNTs表面的富集。最终，这反映了V₂O5@Se NPs/MWCNTs显著的抗菌活性。
