Fabrication and characterization of cytocompatible polypyrrole films inkjet printed from nanoformulations cytocompatible, inkjet-printed polypyrrole films.

Inkjet printed polypyrrole (PPy) films with good uniformity and conductivity are fabricated from a stable, printable PPy nanodispersion, and the cytocompatability of these platforms is demonstrated using PC12 cells. This novel approach to fabricating PPy electrodes and films for tissue engineering and cell stimulation is particularly useful where microstructures are required.
