采用电化学方法在氧化铝模板中制备了镍纳米线，并将其从模板中去除，用发光卟啉进行功能化。使用视频显微镜对纳米线对磁场的响应进行定量。在粘性溶剂中，磁场可用于定向纳米线;在移动的溶剂中，当施加小磁场时，纳米线形成头到高配置的链。链形成的动力学已被定量建模。结果表明，组装纳米线的新方法。
Nickel nanowires prepared by electrochemical growth in alumina templates have been removed from their templates and functionalized with luminescent porphyrins. The nanowires response to magnetic fields was quantified using video microscopy. In viscous solvents, magnetic fields can be used to orient the nanowires; in mobile solvents, the nanowires form chains in a head-to-tall configuration when a small magnetic field is applied. The dynamics for chain formation have been quantitatively modeled. The results demonstrate a new approach for assembling nanowires.
