DNA/AuNP-graphene back-gated field effect transistor as a biosensor for lead (II) ion detection

Abstract

Lead is a very toxic substance that causes metabolic disruption by mimicking the chemical profile of other important ions in the human body. The current technique of determining the presence of lead in drinkable water are simply too expensive to be implemented for large-scale real time monitoring. As an alternative, a sensor based on graphene field effect… (More)
