Nanoparticle transport is the study of how particles at the nanoscale (1-100 nanometers) move and spread in various environments, such as liquids, gases, and porous materials. This research area explores the behavior of nanoparticles in terms of diffusion, advection, and sedimentation, as well as interactions with surfaces and other particles. Understanding nanoparticle transport is crucial for applications in fields such as drug delivery, environmental remediation, and nanotechnology. It involves a combination of experimental techniques, mathematical modeling, and computer simulations to elucidate the mechanisms governing the movement of nanoparticles in different systems.
