Abstract Colloids and interfaces interacting through polar media such as water often carry electric charges and thus Columbic forces play a dominant role in these systems. Presence of the ions carrying multiple charges strongly modifies these forces and the overall behavior of the colloidal dispersions. This thesis focuses on the surface forces between charged interfaces in the presence of the multivalent ions and polyelectrolytes. This is done through comprehensive force measurements by means of Atomic Force Microscopy (AFM). Specifically, colloidal probe AFM is used to study the impact of organic multivalent ions and polyelectrolytes on surface forces between different charged colloidal particles.
