摘　　要：从磁性纳米线的制备、游离纳米线的操控、纳米线有序阵列的表征和应用几个方面综述了磁性纳米线的最新研究进展。详细地介绍了溶胶-凝胶模板法、热还原法等制备磁性纳米线的方法及其应用情况和发展方向。并且针对目前磁性纳米线在实际应用方面存在的问题,着重阐述了游离纳米线操控(包括微流体排列或搭接、自组装和磁场辅助组装、电场/磁场诱捕)的概念、原理、操作方法、表征手段等。在文中还介绍了磁性纳米线的特殊性质及其潜在的应用领域。This paper reviews the latest progresses on preparation, operation, characterization, novel properties and applications of magnetic nanowire arrays. Several methods and the recent developments for preparing magnetic nanowires, such as sol-gel template synthetic, organic gel-thermal reduction, etc., are described. Based on the problems in the use of magnet nanowires, several ways of manipulating nanowires are emphasized, including the array and chain of isolated nanowires in a variety of suspensions, the self-assemble of free nanowires, and the capture of single nanowire under the control of external magnetic fields or electric fields. In addition, the novel properties and the trends on the applications of magnetic nanowires are put forward.
