摘要：

Thermophoresis, or thermal diffusion, consists in particle drift induced by thermal gradients. We discuss the physical mechanisms underlying thermophoresis in colloidal suspensions and macromolecular solutions, and present a general model suggesting thermophoretic measurements as a sensitive probe of particle-solvent interfacial properties. After reviewing recent results obtained by our group on thermal diffusion in charged colloidal systems, we discuss thermophoresis in protein solutions as a specific 'case study'.
