Overcoming evanescent field decay using 3D-tapered nanocavities for on-chip targeted molecular analysis

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 electromagne...
