Probing the dynamics of nanoparticles at oil-water interfaces using high-speed total-internal-reflection dark-field microscopy

Thesis

Particles at fluid-fluid interfaces have a wide range of powerful uses in industry, technology and science. There is therefore a strong interest in exploring the dynamics of these systems to understand and gain more control in applications, as well as for fundamental investigations in condensed matter and statistical physics. Questions remain in particular about what governs adsorption dynamics and inter-particle interactions, and how mixtures of different-sized particles as well as partic...
