N2 - We demonstrate a lateral patch-cramp device structure, made of fused silica, whose patch pipettes were fabricated by using femtosecond laser irradiation and wet etching. The pipettes were an oval-shaped cross-section that was 200 nm × 4 μm, and the minor axis can be controlled on the nano-scale. It is expected that a Giga-seal resistance and its observation using a high magnification microscope can be simultaneously achieved. We confirmed that fluids such as buffer solutions can flow through the nano-pipettes, and some bacteria (B. Subtilis) were successfully trapped at the inlet of a nano-pipette at a given moment.
