Anyone who has made scrambled eggs will have had cause to praise the proper
ties of Teflon. Teflon's highly chemically inert and nonstick nature derive
s from the perfluorinated polymer polytetrafluoroethylene. Perfluorocarbons
have unique and valuable physical properties not found in nature. By incor
porating fluorine into proteins, it might be possible to produce biological
molecules with novel and useful properties.
