Graphene Nanoplatelets for Screen-Printed Nonenzymatic Voltammetric H2O2 Sensors
Abstract
Five types of graphene nanoplatelets were used as the functional phase in polymer composites comprising electrodes for voltammetric sensors. Electrodes were fabricated on poly(ethylene terephthalate) foil by screen-printing technique and then examined for assessment of the electrochemically active area surface, presence of electrical charge, current density, sensitivity and selectivity for hydrogen peroxide—A common biomedical analyte. Concentrations of the analyte as well as other environmental factors (electrolytes concentrations, pH, interferents) were modelling biological conditions of human tear fluid. Nanoplatelets' geometric dimensions were found to affect charge transfer on the electrodes to a greater degree than development of the active surface. This resulted in high oxidation current density on the surface of graphene nanoplatelets with greatest diameter and lowest thickness, yielding high sensitivity (82.02 μA·mm–2·mM–1).
