Abstract
A basic phenomenological model for photoinduced conductivity suitable for a wide variety of photosensitive and photoconductive materials is developed. The modulation of photoconductivity and creation of an inte rnal electric field by spatially modulated light patterns in different materials are described. The moving gratings of photoconductivity and electric fields can be used for optical tweezing of harmful impuritie s in the liquid solutions.
