DNA-Loaded PSf Microspheres Used in Environmental Application

DNA‐loaded porous polysulfone (PSf) microspheres were prepared using a liquid–liquid phase separation technique. The microspheres were then used in environmental application. The DNA‐loaded microspheres were stable in water. They could effectively accumulate the DNA‐binding harmful pollutants and endocrine disruptors, such as ethidium bromide (EB), acridine orange (AO), biphenyl (BP), dibenzofuran (DBF), and dibenzo‐p‐dioxin (DBD), in their aqueous solutions. On the other hand, the microspheres were found to selectively remove heavy metal ions from their aqueous solutions. The DNA‐loaded PSf microspheres have a potential ability to serve as functional materials in environmental application.
