A highly sensitive and selective fluorescence ratiometric sensor membrane for 2,3,3'-trichlorobiphenyl has been achieved, via depositing polypyrrole nanotubes (PPyNTs, the fluorescence indicator) in nano-porous anodic aluminium oxide (NPAAO) template and subsequently immobilizing fluorescein isothiocyanate (as an internal reference) onto the inner walls of the PPyNTs embedded in the NPAAO.

A novel strategy for designing ultrathin polypyrrole skin-coated carbon nanotube (CNT) nanohybrids is demonstrated by vapor deposition polymerization (VDP). The ultrathin skin technology provides a stable immobilization of the mono-disperse Pd nanoparticles (NPs) on the CP-CNT nanohybrid surface, leading to a high-performance hydrogen gas sensor at room temperature.

Sustainable remediation of Cr(vi) removal from contaminated water and real wastewater samples is reported using a polypyrrole–polyaniline copolymer coated green rice husk ash adsorbent.

This paper presents the development of a cheap and rapid electrochemical sensor for ascorbic acid detection. In particular, graphite ink working electrode screen-printed cells was covered by film elecrosynthesized molecularly imprinted polypyrrole (e-MIP); differential pulse voltammetry (DPV) selected method analyte The molecules were successfully entrapped in film, creating recognition sites. ...

Biconductive films, involving the incorporation of an electronically conductive phase within an ionically conductive one, on glassy carbon electrode surfaces have been prepared by electropolymerization to form polypyrrole (PP) in matrices of Nation and the clay, hectorite. These films display electronic conductivity and higher stability than films of PP alone. Electrochemical studies of several...

Among the optical structures investigated for optical sensing purpose, a significant amount of research has been conducted on photonic crystal based sensors. A particular advantage of photonic crystal based sensors is that they show superior sensitivity for ultra-small volume sensing. In this study we investigate polarization changes in response to the changes in the cover index of magneto-opti...

Correction for 'In situ study of the catalytic mechanism for the oxygen reduction reaction on a polypyrrole modified carbon supported cobalt hydroxide cathode in direct borohydride fuel cells' by Haiying Qin et al., Phys. Chem. Chem. Phys., 2013, 15, 9070-9074.

Hollow polypyrrole (PPy) nanospheres with high sodium storage capacity as cathode materials for Na-ion batteries were reported. PPy hollow nanospheres demonstrated high current rate capacity and good cyclability. It was revealed by electrochemical testing and DFT calculation that the as-prepared PPy hollow nanospheres participate in reversible doping/de-doping reactions.
