Electrochemical Immunosensor Based on Fe3O4/PANI/AuNP Detecting Interface for Carcinoembryonic Antigen Biomarker

Reagentless Redox Capacitive Assaying of C-Reactive Protein at a Polyaniline Interface

“…However, the use of Fc, most commonly in self-assembled monolayers (SAMs) on gold, is associated with certain drawbacks, particularly an often compromised redox and thus voltammetric/capacitative baseline stability. , Redox-active conducting polymers are promising candidates in such sensory interfaces, which, because of their high tunability (film thickness, monomer nature, doping state, etc.) and ease of preparation (electropolymerization on various conducting substrates) have been applied in numerous sensors. − As a result of their polymeric, three-dimensional (3D) structure, they are furthermore supportive of a high level of bioreceptor loading (relevant to sensor sensitivity).…”
