Effect of Preparation Additives on the Antimicrobial Activity and Cytotoxicity of Polypyrrole

The search for new biomaterials has increased continuously in recent years and, this context, the application of polypyrrole (PPy) as a promising material function been reported result positive responses, such bioactivity and biocompatibility. In study, PPy was obtained through modifications/adaptations made methodologies previous papers, which focused mainly on conductive properties. use additives synthesis significantly improves biomedical area, depends directly diversity structural morphological parameters. Here, physicochemical characterization helpful to determine structures morphologies resulting samples. addition phytic acid (PA) methyl orange (MO) influenced not only particle morphology size, but also antibacterial activity cytotoxicity. results against Staphylococcus aureus Escherichia coli well negligible cytotoxicity here indicate wide applicability materials wound dressing tissue engineering.
