| Outline of Final Research Achievements |
In this research, a capability of low thickness-to-diameter aspect ratio pore sensors for measuring single-particle shape was investigated. For this, a surrounding-gate electrode-embedded pore was fabricated on a silicon wafer using MEMS technologies. The resistive pulse measurements revealed peculiar feature in the ionic spike signal patterns that reflect the morphologies of single-particles translocated through a channel having appropriate size and length, whereby provided a proof-of-concept of single-particle shape analysis using low-aspect-ratio pores.
