| Outline of Final Research Achievements |
From our preliminary research, we have found that subwavelength-scale structures having cycloid-like cross section is effective for electric field confinement, and it is suitable for highly sensitive biosensing. According to the basis, we have developed the functional structure, fabrication procedure especially obtaining the sensing tip on flexible polymer films, and surface functionalization of the sensor chip. As a result, we achieved sufficient progress towards the realization of a highly sensitive portable sensing system that obviates the spectroscopic measurement with a spectrophotometer. Furthermore, concerning the development on high-speed calculation of electric field propagation, we have found succeeded to derive a new analytical solution for Helmholtz equation in the parabolic coordinate system. This result is expected not only effective for the exploration of functional sub-wavelebgth structures but also to be applied to a wide range of physical phenomena in the future.
