Biocompatibility and antioxidant activity of polypyrrole nanotubes
Source abstract
Abstract
Abstract In the present study antioxidant activity of polypyrrole nanotubes of varying diameter has been investigated. The haemolysis prevention efficiency of the polypyrrole nanotube having highest antioxidant activity has also been studied. Polypyrrole nanotubes have been prepared by chemical polymerization method using FeCl 3 as oxidant with methyl orange (MO) and Cetyl trimethylammonium bromide (CTAB). Structural properties of polypyrrole nanotubes with varying CTAB concentrations have been studied by X-ray diffraction pattern and high resolution transmission electron microscopy (HRTEM). The HRTEM micrographs of polypyrrole nanotubes show significant decrease in diameter upon increase in CTAB concentration. Micro-Raman spectroscopy has been performed to understand the polymer conformation. We demonstrate the antioxidant activity of polypyrrole nanotubes by DPPH free radical assay. The biocompatibility of the polypyrrole nanotubes have been investigated via haemolysis assay.
