金纳米棒自组装的研究进展与未来展望

Research progress and future prospect of self-assembly of gold nanorods

金纳米棒(GNRs)由于其独特的光学和电学性质而备受关注,这些性质取决于其形状、大小和长径比,通过有序的自组装,具有特殊形态的GNRs将表现出更优异的功能化应用。以驱动GNRs自组装的作用力角度出发,综述了过去十几年在GNRs的可控组装方面取得的重大进展,这些经自组装后的纳米材料表现出了更丰富的形态和更优异的光电特性,使其更适用于各种分析物的传感及纳米材料科学领域。

Gold nanorods(GNRs)have attracted much attention because of their unique optical and electrical properties, which depend on their shape, size and aspect ratio.Gold nanorods with special morphology will show more excellent functional applications through orderly self-assembly.From the point of view of the force driving the self-assembly of GNRs, the great progress made in the controllable assembly of GNRs in the past decade is reviewed.these self-assembled nanomaterials show richer morphology and better optoelectronic properties, which make them more suitable for the sensing of various analytes and nanomaterials science.
