Sedimentation of nanoparticles under the action of light pressure forces in liquid media

Abstract

A model of sedimentation of nanoparticles in a uniform light field is considered as an alternative to methods of precipitation in a gravitational field and centrifugation. The exact analytical solution of the one-dimensional nonstationary mass transfer problem in a bounded cell is given. The main parameters of the centrifugal and light-induced sedimentations of nanoparticles are compared.
