Abstract

A direct conjugation of organophosphorus acid anhydrolase (OPAA) with CdS quantum dots was prepared via arrested precipitation within the enzyme matrix. The bio-conjugate was found not only to retain enzyme conformational structure but also to retain enzyme activity and be effective at detecting diisopropyl fluorophosphate (DFP) at the micro molar level.
