based on the Previous studies poly-l-lactide(PLLA) and polyaniline(PANi) and a few other polymers or metals as gold was used but i donʻt know which one has the appropriate properties.
I believe that you mean electric conductivity. For tissue engineering, this is still an open question to my knowledge. There is no optimum material at the moment although some materials show better conductivity than others. Fabrication process is still under study to optimize this effect and it seems that, past the metallic compound, composites with adequate conductive material could be taking over at some point with developing fabrication process.
I am going to make a research related to the electrical conductive scaffolds and we want to electrospun polycaprolactone + chitosan and gold nanoparticles as our scaffold with the highest porosity .
