Apparatus for detecting electrostatic force in solution.

摘要

Disclosed is an apparatus for detecting an electrostatic force in a solution (6) having a sample (3) and a cantilever (8) placed in the solution (6) and designed to detect a force acting between the sample (3) and a tip on the end of the cantilever (8), comprising a cantilever (8) having an end portion whose surface is made of a conductive material, means for applying a voltage to the conductive material on the cantilever end portion, and means for controlling the voltage applied to the conductive material on the cantilever end portion.
