Determination of atropine sulfate using a novel sensitive DNA-biosensor based on its interaction on a modified pencil graphite electrode

A pencil graphite electrode (PGE) modified with MWCNTs, titanium dioxide nano particles and poly dialyldimethylammonium chloride decorated with the ds-DNA were used in order to determine atropine sulfate. The electrochemical oxidation of atropine sulfate bonded on the modified biosensor was used to obtain the analytical signal.213
