Super-resolution near-field imaging on microfluidic structure

A new proposal for biological or microfluidic detection based on super-resolution near-field structure (Super-RENS) proposed by Tominaga is described. The mechanism of the near-field structure we proposed to image microfluid is 'very similar to near-field scanning optical microscope (NSOM). In this paper, we describe our simulation model and results of the electric field distribution in the near field zone and readout signals from the near-field structure to image microfluid. Calculations have demonstrated that the near-field structure can be applied in biomedicine to detect tracing element or image microfluid etc with a high spatial resolution beyond the diffraction limit.
