The aim is to combine the electrochemical properties of both polyaniline and ferrocenium hexafluorophosphate into highly conductive nano composites capable of exhibiting electrochemistry in non acidic media; shuttling electrons between HRP and GCE for biosensor applications.enTooth whitening productsAmperometric biosensorNano-compositesHorseradish peroxide (HRP)Hydrogen peroxideScanning Electron Microscopy (SEM)Cyclic voltammetry (CV)ThesisUniversity of the Western Cape
