OPF-PPy scaffolds were synthesized using three different anions: naphthalene-2-sulfonic acid sodium salt (NSA), dodecylbenzenesulfonic acid sodium salt (DBSA), and dioctyl sulfosuccinate sodium salt (DOSS).  Scaffolds were characterized by ATR-FTIR, XPS, AFM, dynamic mech. anal., elec. resistivity measurements, and swelling expts.  OPF-PPy scaffolds were shown to consist of up to 25 mol % polypyrrole with a compressive modulus ranging from 265 to 323 kPa and a sheet resistance ranging from 6 to 30 × 103 Ohms/square.  In vitro studies using PC12 cells showed OPF-PPy materials had no cytotoxicity and PC12 cells showed distinctly better cell attachment and an increase in the percent of neurite bearing cells on OPF-PPy materials compared to OPF.  The neurite lengths of PC12 cells were significantly higher on OPF-PPyNSA and OPF-PPyDBSA.  These results show that elec. conductive OPF-PPy hydrogels are promising candidates for future applications in nerve regeneration.
