摘要

In this paper a technique for determining surface stress changes at solid-liquid and solid-gas interfaces with an atomic force microscope is presented. To do this the bending of a microfabricated silicon cantilever with differently coated opposite sides is continuously monitored while replacing the medium surrounding it. To demonstrate the feasibility and limitations of the technique, measurements are presented which show the reduction of the surface stress due to the adsorption of different anions on a gold surface coated with a long chain alkanethiol monolayer. The accuracy of the method and its versatility makes this technique very appealing as a basis for a new class of biosensors.
