Paper Abstract

In this study, we proposed a new sensing method using a special SPR chip on which microstructures are fabricated, and performed a principle confirmation of the sensing feasibility using this chip. We examined a fabrication method of micro structures on the SPR chip that has a filter effect by the pillar structure, which can filter the target substance reaching to the detection area of SPR sensing. In order to confirm the filter effect of the micro structure on the SPR chip, we performed the principle confirmation experiment of the SPR sensing system using the fine particles. Next, in order to adapt to the biological molecules measurement, we performed the experiment using yeast cells and demonstrated the filter effect of this chip with the micro structure.
