Popis: Plasmon-enhanced fluorescence is strictly dependent on molecule size and surface position, restricting application of diversely sized molecules. Here, the authors overcome this by introducing a 3D tapered gap plasmon nanocavity with fluidic access and near homogeneous confinement of the electromagnetic fields.
