Molecularly imprinted polymers chemical agent sensors

Nieuwenhuizen and Harteveld [92] have realized a nerve agent dosimeter gas sensor based on the strong interaction between certain metal ions and organophosphorus compounds. In this case, the sensor material contains La(III) 2-bis(carboxymethyl)amino hexadecanoic acid and different factors such as humidity, concentration and layer thickness have been studied and optimized. Using a combination of a metallic complex with a molecular-imprinted polymer, a very sensitive sensor was developed for the detection of soman, a chemical warfare agent (the detection limit was 7 ppt) [93]. The biosensing material is based on a polymer coated onto a fiber-optic probe modified with a luminescent europium detection complex. This complex was... [Pg.502]

New sensors have also been developed for chemical nerve agents and nerve agent analogues or simulators. The detection of a nerve agent analogue, pinacolyl methylphosphonate (PMP), has been demonstrated using an electrochemically, molecularly-imprinted polymer (MIP) polythiophene film set on a quartz crystal microbalance (QCM) transducer surface. " A nerve gas sensor for dimethyl methylphosphonate (DMMP) has also been based on chemically (p-phenylenediamine)-reduced graphene... [Pg.278]
