Glucose fast-response amperometric sensor based on glucose oxidase immobilized in an electropolymerized poly(o-phenylenediamine) film.
To the authors' knowledge, this represents the first report of a membrane capable, at the same time, of immobilizing GOx and rejecting ascorbate, and the interesting electrode behavior can be rationalized by using an existing model predicting the amperometric response of an immobilized GOx system.

Inhibitive determination of metal ions by an amperometric glucose oxidase biosensor: Study of the effect of hydrogen peroxide decomposition
Abstract An amperometric glucose biosensor based on glucose oxidase immobilized in electrosynthesized poly-o-phenylenediamine was successfully applied to the determination of a wide group of heavyExpand
A new amperometric nanostructured sensor for the analytical determination of hydrogen peroxide.
Cyclic voltammetry experiments yielded evidence that silver nanoparticles facilitate hydrogen peroxide reduction, showing excellent catalytic activity, and the constructed sensors suitable for peroxide determination in aqueous solution. Expand
An x‐ray photoelectron spectroscopic study of some chromium–oxygen systems
A series of pure and mixed chromium standards has been analysed by x-ray photoelectron spectroscopy in order to obtain a sufficiently homogeneous and self-consistent set of spectral parameters to beExpand
Preparation and characterization of molecularly imprinted mussel inspired film as antifouling and selective layer for electrochemical detection of sulfamethoxazole
Abstract The present work describes the development of a novel simple and cheap electrochemical sensor based on molecularly imprinted polydopamine, for the detection of sulfamethoxazole (SMX) anExpand
MIP sensors – the electrochemical approach
This review highlights the importance of coupling molecular imprinting technology with methodology based on electrochemical techniques for the development of advanced sensing devices and describes possible approaches proposed in the literature on this topic. Expand
Development of a sensor prepared by entrapment of MIP particles in electrosynthesised polymer films for electrochemical detection of ephedrine.
A voltammetric sensor for (-)-ephedrine has been prepared by a novel approach based on immobilisation of an imprinted polymer for ephedrine (MIPE) in an electrosynthesised polypyrrole (PPY) film, which showed a response which was distinctly lower than the MIP response for the same concentration of the template.

X-ray photoelectron spectroscopy characterization of poly(2,3-diaminophenazine) films electrosynthesised on platinum
Abstract Films of poly(2,3-diaminophenazine) (PDAPh) were obtained on platinum substrates by electropolymerization (cyclic voltammetry, CV) of the monomer in acidic solutions. Limited investigationsExpand
Molecularly imprinted electrosynthesized polymers:  new materials for biomimetic sensors.
Molecular imprinting electropolymerization is proposed as a possible strategy for the preparation of new materials with molecular recognition properties to be applied in biomimetic sensors. Expand
A rapid and simple method for the determination of 3,4-dihydroxyphenylacetic acid, norepinephrine, dopamine, and serotonin in mouse brain homogenate by HPLC with fluorimetric detection.
A fast and simple isocratic high-performance liquid chromatography method for the determination of 3,4-dihydroxyphenylacetic acid, dopamine, norepinephrine and serotonin in animal tissues employing the direct fluorescence of the neurotransmitters is described. Expand
