Cytotoxicity of poly(p-phenylenediamine)

Autor: Petra Rejmontová, Petr Humpolíček, Petr Saha, Patrycja Bober, Věra Kašpárková, Jaroslav Stejskal, Zdenka Kuceková

Publikováno v: Chemical Papers. 71:367-372

Although poly(p-phenylenediamine) is an electric non-conductor, it exhibits, analogously to conducting polymers, redox activity and could, therefore, find applications in biomedicine. In the current work, the cytotoxicity of poly(p-phenylenediamine)
