| Our group studies the physics and physical chemistry of soft matter, including simple liquids, polymers and bio-macromolecules. In particular, we study their behaviour and interactions at surfaces, interfaces and in confined geometries. We employ a variety of experimental techniques, with emphasis on direct Angstrom level measurements of forces between atomically-smooth surfaces, and between adsorbed or confined molecules. We have developed force-measuring methods with resolution and sensitivity some 3 - 4 orders of magnitude better (per molecule) than scanning probe techniques (e.g.AFM), and use these to probe both dynamics and equilibrium properties. Some recent projects are outlined below. Click on the pictures for more information. |
