Abstract

DNA-loaded porous polyethersulfone (PES) particles are fabricated using a liquid–liquid phase separation technique. The particles are then used for environmental applications. Both the DNA-loaded porous PES particles and the DNA-loaded PES porous particle column could accumulate and remove DNA intercalating pollutants, such as ethidium bromide, acridine orange, endocrine disruptors, and heavy metal ions. The microsphere column shows more high removal efficiency. These results proved that the DNA-loaded porous particles have the potential to serve as absorbents for environmental applications. © 2005 Wiley Periodicals, Inc.
