Sonochemically fabricated enzyme microelectrode arrays for the environmental monitoring of pesticides.
Biosens Bioelectron. 2004 Nov 01; 20(4):765-72.BB

Abstract

This paper describes the development of a novel sonochemically fabricated microelectrode based acetylcholinesterase and polyaniline carbon/cobalt phthalocyanine biosensor for the ultra-sensitive determination of pesticides. Arrays of this type are fabricated using microelectrode templates with population densities of 2 x 10(5) cm(-2). The enzymatic response of the sensors is inhibited upon incubation with the pesticide and in this report it is shown that paraoxon may be determined down to concentrations of 1 x 10(-17) M. This sensitivity has thus far not been achieved and mechanisms accounting for the enhancement of the sensitivity reported here are discussed.
