Microbial contamination of water represents a great threat to the public health that has attracted worldwide attention. In this work, polypyrrole magnetic nanoparticles (Fe3O4@PPy NPs) with sterilization properties were fabricated. More specifically, Fe3O4@PPy NPs obtained via aqueous dispersion polymerization and an in situ chemical oxidative exhibited cationic surface high photothermal conver...

Conducting polypyrrole is a biological compatible polymer matrix wherein number of drugs and enzymes can be incorporated by way of doping. The polypyrrole, which is obtained as freestanding film by electrochemical polymerization, has gained tremendous recognition as sophisticated electronic measuring device in the field of sensors and drug delivery. In drug delivery the reversing of the potenti...

Large area highly uniform and ordered polypyrrole nanowire and nanotube arrays were fabricated by chemical oxidation polymerization with the help of a porous anodic aluminium oxide (AAO) template. Under 0.2 moL/L pyrrole (H2O) and 0.2 moL/L FeCl3 (H2O) pattern, polypyrrole nanowire arrays were obtained after 2.0 hours polymerization reaction in a two-compartment reaction cell. When the reaction...

Organic semiconductors have been the objects of considerable attention in recent years, both as electrodes and photoelectrods in different applications. Radiation-induced and electrochemical modification of polypyrrole film by incorporating of large electro-active organic molecules is investigated in this paper. Introduction in the polypyrrole (PPy) of methylene blue as counterion has a strong ...

The aim of this review is to summarize the recent progress in the fabrication of efficient nanostructured polymer-based sensors with special focus on polypyrrole. The correlation between physico-chemical parameters, mainly morphology of various polypyrrole nanostructures, and their sensitivity towards selected gas and volatile organic compounds (VOC) is provided. The different approaches of pol...

A simple and sensitive electrochemical immunosensor with impedance labelless detection and novel data processing method was investigated. One-step copolymerization was used to electrochemically deposit an antibody impregnated polypyrrole film on a glassy carbon electrode surface for the immunosensor. Impedance measurements provided a labelless or reporterless method to detect antibody (Ab)-anti...

Polypyrrole is one of the important conductive polymers that are widely used in energy storage systems, biosensors and electronics. The electrochemical synthesis of polypyrrole has advantages of simple process, mass production and low cost. In this study, polypyrrole thin films were deposited on different electrode substrates by cyclovoltammetric (CV), galvanostatic and potentiostatic depositio...

INTRODUCTION The development of conducting colloids stemmed from applications driven needs for proeessable conducting polymers. Because conducting polymers are aggregated in nature, due to their conjugated backbones, the preparation of colloidal systems of these aggregates is an attractive approach to by-passlng the intractability problem. The reason for focussing on the two particular colloida...

A novel protocol for precisely coating individual multiwall carbon nanotubes (MWCNTs) with an ultrathin layer of polypyrrole was developed. The nanocoated MWCNTs were successfully prepared by in situ chemical deposition of polypyrrole in an aqueous suspension of MWCNTs. The coating layer was very uniform and the thickness of the layer was determined by controlling the monomer concentration used...
