Development of a molecularly imprinted polymer for uric acid sensing based on a conductive azopolymer: Unusual approaches using electrochemical impedance/capacitance spectroscopy without a soluble redox probe
(2021-09-15)
In the present study, we report the use of an electrochemical sensor for uric acid using a molecularly imprinted polymer (MIP) as a molecular recognition platform. The MIP was based on an azopolymer electropolymerized in ...
Coupling between proton binding and redox potential in electrochemically active macromolecules. the example of Polyaniline
(Elsevier Science Sa, 2013-10-15)
In this work it is investigated the coupling between the redox potential and the extent of proton binding in electrochemically active polymers, for the particular case of Polyaniline (Pani). To this purpose, the degree of ...
Metal-ion responsive redox polyelectrolyte multilayers
(Royal Society of Chemistry, 2010-10)
We present polyelectrolyte multilayer modified electrodes exhibiting novel chemically responsive redox behaviour due to the combination of both redox and metal-ion–ligand functionalities on the same sites.
Methylated DNA impedimetric immunosensor based on azo-polymer-AuNPs dots and 5-methylcytosine antibody using dissolved oxygen as a redox probe
(2022-03-01)
The present work describes the development of an electrochemical immunosensor for the direct determination of methylated DNA using dissolved oxygen as the redox probe. The oxygen-sensitive response is possible due to the ...
Electroactive polymers made by loading redox ions inside crosslinked polymeric hydrogels. Effects of hydrophobic interactions and solvent dynamics
(Pergamon-Elsevier Science Ltd, 2016-11)
Electroactive polymers are made by loading redox complexes inside different polymeric crosslinked hydrogels. A redox cation (tris(phenanthroline)iron(II) (TPFeII) is sorbed in anionic, neutral and cationic hydrogels while ...
Redox-Driven Reversible Gating of Solid-State Nanochannels
(American Chemical Society, 2019-08)
The design of an electrochemically addressable nanofluidic diode is proposed, which allows tunable and nanofluidic operations via redox gating under electrochemical control. The fabrication process involves the modification ...
Redox commuting properties of polyaniline in hydrochloric, sulphuric and perchloric acid solutions
(Elsevier Science Sa, 2018-05)
In the present work we have studied the pH dependence of the voltammetric response of polyaniline (Pani) in three different electrolytic media: HCl, H2SO4 and HClO4 at constant ionic strength. The electrochemical stability ...
