Scientists report a new methodology for surface modification of Teflon. The ease and efficiency of this approach and its rather robust character offer a number of interesting future perspectives.
Jean-Marc Vincent and his colleagues at the University Bordeaux, in France, have modified the Teflon membranes with a fluorophilic copper(II)-carboxylate complex. They believe that this may prove very useful towards developing passive samplers for the detection of contaminants of aquatic ecosystems, such as pharmaceutical compounds. The recycling of catalysts (modified by pyridyl tags or other groups that can bind to copper) and the purification of histidyl-tagged proteins are other examples of potential applications.
