In our experiments we investigate the interaction occuring between metallic nanostructures and fluorophores, especially emission\/absorption enhancements or quenching. On the other hand, for elongated structures, like nanowires, also similar effect can be found, in which energy can be transferred in micromenter-scale ranges by surface plasmon polaritons.<\/p>\n<\/div><\/div>\n\n\n\n<p><strong>Related papers:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>K.
