Placement of nanoscopic entities in the optical near field of a structure such as a plasmonic nanoantenna or the aperture of a scanning near-field optical microscopy (SNOM) remains a nontrivial task, which often requires sophisticated nanofabrication techniques. Here, we show that the fluidity and diffusion of lipid molecules in bilayer geometries can be exploited for facile delivery of nano-objects such as organic dye molecules, semiconductor quantum dots, and gold nanoparticles to the near field of well-defined surface structures. We demonstrate this in three different scenarios with substantial plasmonic enhancement of fluorescence.

负载的脂质双层作为随机传送带，用于输送到纳米级结构的近场


在等离子体纳米天线等结构的光学近场或扫描近场光学显微镜 （SNOM） 的孔径中放置纳米级实体仍然是一项艰巨的任务，通常需要复杂的纳米制造技术。在这里，我们表明脂质分子在双层几何形状中的流动性和扩散可用于将纳米物体（如有机染料分子、半导体量子点和金纳米颗粒）轻松递送到明确表面结构的近场。我们在三种不同的场景中证明了这一点，荧光的显着等离子体增强。
