主要内容:

    Nanoscience and nanotechnology as an emerging interdisciplinary research area has caught a lot of attention in recent years. Although a wide range of nanomaterials with novel properties different from bulk samples can now be synthesized; there is still a long way for nanoscience and nanotechnology to direct impact our everyday life. Significant efforts are needed to improve nanomaterials fabrication reproducibility and quality control; to increase nanomaterials output and to reduce cost; to understand coupled nano-phenomena; and to integrate nanomaterials with existing technology and devices. Currently, the most used nanomaterials are spherical particles. To introduce anisotropy and multifunctionality, there is increasing interests in the development of nonspherical nanostructures such as nanowires and nanotubes. These structures are able to deliver novel electrical, thermal, mechanical, optical, magnetic, and biomedical functionalities that are unobtainable by nanoparticles. Here we will introduce the template assisted electrodeposition method for magnetic nanowires synthesis. We will show how magnetic properties of nanomaterials can be designed and tuned through nanofabrication in terms of magnetic anisotropy, magnetization reversal and finite size effects. Effective magnetic field manipulation of these nanowires in liquids for alignment and rotation control has been realized. Potential sensing and bio-medical applications of magnetic nanowires in magnetic resonance imagining (MRI), targeted drug delivery and tissue engineering will be discussed.
