Abstract

A method of controlling liquid movement in a chemical device comprising a porous structure involved applying an electrical potential to generate an electroosmotic force in the porous structure so as to propel a liquid through the porous structure. Also the porous structure is used to resist or prevent flow of a liquid through the porous structure in response to hydrostatic force.
