Abstract Scope The challenge to develop high-performance biosensors from nanocomposites with broader electrical conductivity, molecular sensitivity and specificity remains is elucidated by designing and synthesizing scalable, metal nanoparticles-grafted functionalized graphene overcoat with nanostructured polyaniline nanocomposites. The versatility of the nanocomposite performance was corroborated by altering the size, areal density and morphology of electrodeposited gold and silver nanoparticles (NPs) on nitrogenated functionalized graphene (NFG) and changing the density of the electropolymerized polyaniline (PANi) onto NFG. Gold (Au) and silver (Ag) NPs are selected owing to their higher electrical conductivity, facile synthesis and easier processability. The critical modification of these electrode architectures (NFG/Ag/PANi or NFG/Au/PANi) on fluorinated tin oxide electrodes increased the conductivity and reduced the charge transfer resistance while studying electrochemical properties. The biosensing was demonstrated for ascorbic acid commonly found in blood serum. These nanocomposites are also applicable for electrocatalysis, energy storage and conversion systems and enriching biofuel cell development.
