我们已经开发了各种长度的烟草花叶病毒（TMV）纳米棒的中央通道内的钯纳米线（Pd NWs）的模板合成的方法。我们表明，均匀的4 nm直径的钯纳米线可以通过选择性生长在这些通道内，包括封盖试剂，聚（乙烯基吡咯烷酮）（PVP 30 K）和减少金属前体金属钯与抗坏血酸。可以通过改变纳米棒模板的长度和/或通过改变反应条件来控制Pd NW的长度。我们还证明了TMV纳米棒的金（Au）-钯（Pd）原位金属化，导致产生连接到其末端的Pd纳米线6 nm金纳米颗粒。所产生的材料在纳米器件的构建中具有许多潜在的应用。
We have developed methods for the templated synthesis of palladium nanowires (Pd NWs) within the central channel of tobacco mosaic virus (TMV) nanorods of various lengths. We show that uniform 4 nm diameter Pd NWs can be produced by selective growth within these channels by including the capping reagent, poly(vinyl-pyrrolidone) (PVP30K) and reducing the metal precursor to metallic palladium with ascorbic acid. The length of the Pd NWs can be controlled either by varying the length of the nanorod templates and/or through alterations to the reaction conditions. We have also demonstrated bimetallic gold (Au)-palladium (Pd)in-situmetallization of TMV nanorods resulting in the production of Pd NWs 6 nm gold nanoparticles attached to their ends. The materials produced have many potential applications in the construction of nanoscale devices.
