摘要
利用种子法和水热合成技术,分别在常规条件下和阵列式微通道中制备氧化锌(Zn O)纳米棒。采用扫描电子显微镜(SEM)、X射线衍射(XRD)等分析方法表征Zn O纳米棒的表面形貌特点和晶体结构。结果表明:微通道中制备的Zn O纳米棒的比表面积、结晶度和c轴取向性均有较大程度的提高。同时,建立了基于阵列式微通道的Zn O纳米棒生物荧光检测方法,利用Zn O纳米棒可显著增强荧光信号,对异硫氰酸荧光素标记的羊抗牛Ig G抗体的检测限为1×10-4μg/m L。
The ZnO nanorods are hydrothermally grown starting from a ZnO seed layer with conventional method and in microchannel arrays. The structures of prepared ZnO nanorods are characterized using a scanning electron microscopy（ SEM） and their crystalline properties are analyzed by X-ray diffraction（ XRD）. The results show that the surface area,crystalline and c-axis orientation of ZnO nanorods have been improved significantly. Meanwhile,bioluminescence detection of ZnO nanorods has been established based on microchannel arrays,and fluorescence signals have been enhanced on ZnO nanorods platforms and detection limit of FITC-anti IgG is 1 × 10^-4μg / m L.
