In recent years there has been a growing interest in the interactions of fluorophores with metallic nanostructures or nanoparticles. The spectra properties of fluorophores can be dramatically modified by near‐field interactions with the electron clouds present in metals. Near‐field interactions are those occurring within a wavelength distance of an excited fluorophore. These interactions modify the emission in ways not seen in ensemble fluorescence experiments. In this review we provide an insightful description of the photophysics of metal plasmons and near‐field interactions. Additionally, we summarize recent works on single‐molecule studies on metal‐fluorophore interactions and suggest how these effects will result in new classes of experimental procedures, novel probes, bioassays and devices.

金属纳米结构附近单分子荧光的修饰。

近年来，人们对荧光团与金属纳米结构或纳米颗粒的相互作用越来越感兴趣。荧光团的光谱特性可以通过与金属中存在的电子云的近场相互作用来显着改变。近场相互作用是在激发荧光团的波长距离内发生的相互作用。这些相互作用以集合荧光实验中未见的方式改变发射。在这篇综述中，我们对金属等离子体激元和近场相互作用的光物理学进行了深入的描述。此外，我们总结了最近关于金属荧光团相互作用的单分子研究的工作，并提出了这些效应将如何产生新类别的实验程序、新颖的探针、生物测定和设备。
