Abstract:
We made nano-patterning of NaCl on the clean Au-Substrate & Mica using Nanopipette based on the QTF-AFM (Quartz Tunning Fork-Atomic Force Microscopy) nano-scaled water ejection system. The NaCl is ionized in liquid solution (we used deionized-Water) which can be easily extruded out from the hole of nanopipette, and the Na+ and Cl- ions would be resolved and be crystallized without liquid. After filled the NaCl solution in the nanopipette, we applied electric field to eject out the solution on the clean Au-Substrate and Mice. Used nanopipette’s apex diameter was 100~1000 nm which was fabricated by commercial pipette puller (P-2000). With QTF-AFM feedback system, we could sustain the distance between tip and substrate. The nano-patterned size could be controlled by the nanopipette’s size and applied electric field.
