Mass transport effect of mesoscopic domains in the amperometric response of an electroactive species: Modeling for its applications in biomolecule detection
(Elsevier Science Sa, 2010-02)
We report the numerical simulation of an electrochemical system compromising a mesoporous material placed at a close distance of a working electrode. The effect of mesoscopic domains to the amperometric response of an ...
Amperometric detection of D-sorbitol with NAD+-D-sorbitol dehydrogenase modified carbon paste electrode
(Elsevier Science, 2000-11)
A biosensor based on modified carbon paste electrodes for the amperometric detection of D-sorbitol is described. Carbon paste electrodes were modified by D-sorbitol dehydrogenase (SDH) and nicotinamide adenine dinucleotide ...
Paper-based enzymatic platform coupled to screen printed graphene-modified electrode for the fast neonatal screening of phenylketonuria
(Elsevier Science, 2018-11-11)
Introduction: The PKU is an inborn error of amino acid metabolism, in which phenylalanine (Phe) accumulated in the blood causing alterations at the central nervous system. We report a novel paper-based enzymatic platform ...
Ca2+-independent and voltage-dependent exocytosis in mouse chromaffin cells
(Wiley Blackwell Publishing, Inc, 2020-04)
Aim: It is widely accepted that the exocytosis of synaptic and secretory vesicles is triggered by Ca2+ entry through voltage-dependent Ca2+ channels. However, there is evidence of an alternative mode of exocytosis induced ...
Amperometric biosensor based on laccase immobilized onto a nanostructured screen-printed electrode for determination of polyphenols in propolis
(Elsevier Science, 2018-08)
This work describes the preparation of an electrochemical biosensor for polyphenols determination in propolis samples. The biosensing scheme is based on a nanocomposite film of laccase enzyme (Lac) immobilized on gold ...
Amperometric flow injection analysis as a new approach for studying disperse systems
(Pergamon-Elsevier Science Ltd, 2009-12)
Fast and simple quantitative determination in dispersed systems (layered double hydroxides - LDHs - suspensions in aqueous solutions) was performed by a procedure that couples flow injection and amperometric detection ...
Screening for cystic fibrosis via a magnetic and microfluidic immunoassay format with electrochemical detection using a copper nanoparticle-modified gold electrode
(Springer Wien, 2016-10)
This article describes a microfluidic electrochemical immunoassay that features two strategies, viz. (a), the incorporation of magnetic nanoparticles (MNPs) into the central microfluidic channel and acting as a bioaffinity ...

Imaging local electrochemical current via surface plasmon resonance
(American Association for the Advancement of Science, 2010-03)
We demonstrated an electrochemical microscopy technique based on the detection of variations in local electrochemical current from optical signals arising from surface plasmon resonance. It enables local electrochemical ...
