NANO-LIQUID/LIQUID WAVEGUIDE COUPLING BY EVANESCENT TUNNELING EFFECT FOR BIOMOLECULE IMAGING APPLICATIONS

摘要

In this paper, a nano-liquid/liquid waveguide coupling based on evanescent tunneling effect is demonstrated. For the first time, the feature size in the fluidic beyond the diffraction limit with changes as small as 1 nm can be imaged in the microchannel. The evanescent coupling length can be tuned by the flow rates and the fluids materials flexible than semiconductor ones. This implies that single molecule imaging can be achieved with the developed near field interaction technique.
