Schematic representation of (i) expected PPy morphologies: (a) nanotubular and (b) globular, and (ii) biosensor construction steps for antibody detection. Steps: (a) Functionalization though SAM formation, (b) activation via EDC:NHS, (c) immobilization of N-Protein, (d) Blocking via BSA and (e) antibody detection. BSA, bovine serum albumin; EDS, energy-dispersive X-ray spectroscopy; NHS, N-hydroxysuccinimide; PPy, polypyrrole; SAM, self-assembly monolayer.
