多孔模板内的顺序电沉积可用于制备尺寸和成分可调的条状纳米线。沿导线长度的组成变化可用于结合电功能、光学对比度和/或所需的表面化学。纳米线可以用适合组装或生物传感的化学或生化试剂来功能化。因此，这些颗粒作为纳米电子的构建块和用于生物和非生物标记应用的“条形码”是很有意义的。在这篇文章中，我们简要地讨论了条状金属纳米线的合成和光学读出，以及这些潜在应用的进展。
Sequential electrodeposition within a porous template can be used to prepare striped nanowires with tailorable dimensions and composition. Variations in composition along the length of the wire can be used to incorporate electrical functionality, optical contrast, and/or desired surface chemistry. Nanowires can be functionalized with chemical or biochemical reagents appropriate for assembly or biosensing. Therefore, these particles are interesting as building blocks for nanoscale electronics and as "barcodes" for both biological and non-biological tagging applications. In this article, we briefly discuss the synthesis and optical readout of striped metal nanowires, as well as progress towards each of these potential applications.
