Para-substituted sulfonic acid-doped protonated emeraldine salt nanobuds: a potent neural interface targeting PC12 cell interactions and promotes neuronal cell differentiation

Surface functionalized protonated emeraldine salt (PES) synthesized at 0.18 V provide robust electrically conductive system with low surface resistivity (81.18 mΩ). The PES show ability of cell-type specific microenvironment supporting PC12 cells for neural differentiation.
