基于它们的电子导电性行为，金属纳米线可能具有从互连到传感器的分析应用。我们在本文中提出了一种电化学方法合成钼和钯金属纳米线的直径范围从几十纳米到一微米，长度毫米。纳米线通过在石墨表面上存在的台阶边缘处电沉积金属来制备。这些纳米线可用于连接金属纳米颗粒（Ni、Au等）。一旦转移到聚合物铸件中，它们就可以作为传感器工作。我们描述了如何操纵这些纳米线来制造用于分析化学的器件，并且作为这种纳米器件的一个例子，给出了第一个基于纳米线的氢气（H2）传感器的特性的详细概述。版权所有© 2002年约翰威利父子有限公司。
Based on their electronic conductivity behaviour, metallic nanowires may have analytical applications ranging from interconnects to sensors. We present in this paper an electrochemical method for synthesizing Mo and Pd metal nanowires ranging in diameter from a few tens of nanometres up to one micrometre, with millimetre lengths. Nanowires are prepared by the electrodeposition of metal at step edges present on a graphite surface. These nanowires can be used to connect metal nanoparticles (Ni, Au, etc.). Once transferred in a polymer cast, they can operate as sensors. We describe how these nanowires may be manipulated to make devices for analytical chemistry and, as an example of such nanodevice, a detailed overview of the characteristics of the first nanowire‐based sensor of hydrogen gas (H2) is given.
