Colloid Science is the study of material dispersions which rely on molecular and nano-scale phenomena to impart key properties. Such colloidal phenomena, which include adsorption, aggregation and self assembly, are dictated by surface interactions. Colloid and surface science are thus inextricably related, and are enabling disciplines for global industries, including minerals processing, water treatment and pharmaceutical formulation. They are also key ingredients for the so-called 'nanotechnology revolution'.
