Probing the double layer: effect of image forces on AFM.

Frederick Sachs.   

Abstract

Force probes such as AFM tips or laser trap latex beads have a dielectric constant much less than that of the water that they displace. Thus when a probe approaches a charged surface under water it will be repelled simply based upon the image forces, and these can be of nN magnitude.
