Fabrication of Photonic Force Devices for Biomolecule Dynamics

We microfabricated the plasmonic nanopore with ~ 1 nm on top of the pyramid for single molecule dynamics. This plasmonic micro device provides huge photon transmission through the fabricated nanochannel on the top of the pyramidal structure. This can generate the huge photonic pressure gradient between the free space and nanopore inside. The huge pressure gradient can be attributed to the resonance transmission between the fabricated V groove cavity and the nanosize waveguide formed during the metal deposition. This fabricated huge photonic device can be utilized as biomolecule translocation and single molecule dynamics.
