NANOSCALE PROBE STRUCTURE AND APPLICATION THEREOF

摘要

A nanoscale probe structure, including: a first probe having a tip top end and a second probe having a planar top end, wherein a metallic layer coats the on the tip top end, an insulating layer coats around the tip top end of the first probe; and a metallic layer coats on the planar top end, an insulating layer coats around the planar top end of the second probe. The structure of present invention can applied in atomic force microscopy to measure the electricity physiology signal inside and outside the cell membrane, which can limit the measure region to specific little area for the measure of electricity physiology signal and effectively decrease the miscellaneous noise disturbance from other region.
