Development of a bioelectrode fabricated with a multilayer thin film of poly(diallyldimethylammonium)/gold-nanoparticle/lactate oxidase for analysis of L-lactate in food samples
(Elsevier Science Sa, 2017-01)
Multilayer films made of poly(diallyldimethylammonium) (PDDA), gold nanoparticles (AuNP) of 10 nm diameter and lactate oxidase (LOx), were built for the first time, by layer-by-layer (LBL) assembly technique onto both ...
Carbon Nanotubes Paste Electrodes. A New Alternative for the Development of Electrochemical Sensors
(Wiley VCH Verlag, 2007-12)
In this work we summarize the recent activities of our group regarding the analytical performance of a new compositematerial, the so-called carbon nanotubes paste electrode (CNTPE) obtained by dispersion of multiwall ...
Milk lactate determination with a rotating bioreactor based on an electron transfer mediated by osmium complexes incorporating a continuous-flow/stopped- flow system
(Elsevier Science, 2003-11)
The high sensitivity that can be attained using a bienzymatic system and mediated by the redox polymer [Os(bpy)2 ClPyCH2NHpoly(allylamine)] (Os-PAA), has been verified by on-line interfacing of a rotating bioreactor and ...
A biosensor based on immobilization of lactate oxidase in a PB-CTAB film for FIA determination of lactate in beer samples
(Sociedade Brasileira de Química, 2008)
An amperometric lactate biosensor with lactate oxidase immobilized into a Prussian Blue (PB) modified electrode was fabricated. The advantage of using cetyltrimethylammonium bromide (CTAB) in the electrodeposition step of ...
Improvement of the amperometric response to l-lactate by using a cationic bioinspired thymine polycation in a bioelectrode with immobilized lactate oxidase
(Elsevier, 2013-01)
We report the electroanalytical properties of an amperometric bioelectrode containing L-lactate oxidase (LOx) immobilized on glassy carbon electrode with a hydrogel film composed of laponite and different amounts of a novel ...
Imaging resolution of biocatalytic activity using nanoscale scanning electrochemical microscopy
(Springer, 2018-08)
Scanning electrochemical microscopy represents a powerful tool for electro(chemical) characterization of surfaces, but its applicability has been limited in most cases at microscale spatial resolution, and the greatest ...
Paper microfluidic device using carbon dots to detect glucose and lactate in saliva samples
(2021-03-05)
Bioanalyses are commonly performed with blood or serum samples. However, these analyses often require invasive and painful blood collection using a needle or finger pricking. Saliva is an alternative and very attractive ...
Estudo da toxicologia e da farmacologia do 2-feniletinilbutil-telúrio em roedores
(Universidade Federal de Santa MariaBRBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica Toxicológica, 2013-08-05)
The organotellurium compounds have been the subject of research due to their pharmacological and toxicological properties. It is believed that the main mechanism involved in the toxicity of these compounds is the ability ...
