Biocompatibility implications of polypyrrole synthesis techniques

Green synthesis of nano polypyrrole using urea-hydrogen peroxide

Polypyrrole is one of the most useful conductive polymers, but green synthesis of this polymer has been restricted until now. The objective of the present paper is green synthesis of nano polypyrrole (PPy) by oxidative polymerization using urea-hydrogen peroxide. It was found that conductivity and morphology of polypyrrole are highly dependent on the reaction conditions such as the molar ratio ...

Polypyrrole Synthesis via Carboxymethylcellulose-iron Complexes

Polypyrrole (PPy) was chemically synthesised at two pH levels (pH = 2 and unadjusted pH, i.e. 6.6) using pre-formed carboxymethylcelluloseiron (CMC-Fe) complexes. The CMC-Fe complexes were prepared at a fixed CMC concentration, i.e. 5.5x10 mol/L, and with an increasing FeCl3 amount (from 4x10 to 5x10 mol/L). The quantity of iron bound to CMC was determined by the inductively coupled plasma (ICP...

Biocompatibility of Polypyrrole with Human Primary Osteoblasts and the Effect of Dopants

Polypyrrole (PPy) is a conducting polymer that enables controlled drug release upon electrical stimulation. We characterized the biocompatibility of PPy with human primary osteoblasts, and the effect of dopants. We investigated the biocompatibility of PPy comprising various dopants, i.e. p-toluene sulfonate (PPy-pTS), chondroitin sulfate (PPy-CS), or dodecylbenzenesulfonate (PPy-DBS), with huma...

Polypyrrole Composites: Electrochemical Synthesis, Characterizations and Applications

The electronically conducting polymers (ECPs), such as polypyrrole (PPy), polythiophene (PT) and polyaniline (PANI) are known to possess unusually high electrical conductivity in the doped state. Due to this, these materials have been of great interests for chemists as well as physicists since their electrical properties were reported (Diaz et al., 1979). The ECP films behave like a redox polym...
