Abstract
Surface forces acting between particles and different contributions to the forces are outlined with particular attention paid to the colloidal stability with nanosize particles. This is followed by a discussion of surface forces for nanosize particles and an introduction of a novel nanosize colloidal probe technique in an atomic force microscope.
