Carbon nanotubes non-covalently functionalized with cytochrome c: A new bioanalytical platform for building bienzymatic biosensors
(Elsevier Science, 2016-09)
We report for the first time the use of glassy carbon electrodes (GCE) modified by drop-coating with multi-walled carbon nanotubes (MWCNTs) dispersed in cytochrome c as platform for the construction of bienzymatic biosensors, ...
Del canario al biosensor
(Universidad Nacional de Córdoba. Facultad de Ciencias Químicas, 2018-12)
Un breve comentario sobre un proyecto en el cual estamos comenzando a trabajar y cuya motivación principal es lograr desarrollar biosensores basados en mecanismos de transducción fotoelectroquímica con aplicación concreta ...
Multi-walled carbon nanotubes non-covalently functionalized with Polyarginine: A new alternative for the construction of Reagentless NAD + /Dehydrogenase-based Ethanol Biosensor
(Wiley VCH Verlag, 2019-05)
This work reports for the first time the development of a reagentless enzymatic amperometric biosensor for ethanol based on the use of a glassy carbon electrode (GCE) modified with multi-walled carbon nanotubes (MWCNTs) ...
Amperometric biosensor for direct blood lactate detection
(American Chemical Society, 2010-07)
An amperometric sensor for lactate quantification is presented. The developed biosensor requires only 0.2 U of lactate oxidase, which is immobilized in a mucin/albumin hydrogel matrix. By protecting the platinum surface ...
Fabrication of a novel biosensor for biosensing of bisphenol A and detection of its damage to DNA
(Elsevier Science, 2019-04)
In this work, a novel electrochemical biosensor has been fabricated based on step-by-step modification of aglassy carbon electrode (GCE) with methylene blue (MB)-DNA/multiwalled carbon nanotubes (MWCNTs)-chitosan (CS)/palladium ...
Intellectual modifying a bare glassy carbon electrode to fabricate a novel and ultrasensitive electrochemical biosensor: Application to determination of acrylamide in food samples
(Elsevier Science, 2018-01)
Acrylamide (AA) is a neurotoxin and carcinogen which is mainly formed in foods containing large quantities of starch processed at high temperatures and its determination is very important to control the quality of foods. ...
How low does the oxygen concentration go within a sandwich-type amperometric biosensor? Part 2: Theory for PPO biosensors
(Elsevier Science SA, 2015-02)
A mathematical model to describe the amperometric response of a sandwich-type biosensor containing polyphenol oxidase as the recognition catalytic element is proposed. The model was solved numerically and the resulting ...
Whole-cell biosensors: research and patents
(Bentham Sci. Pub., 2010-07)
In the last ten years several research articles and patents related to the obtaining and uses of whole-cell biosen- sors (WCB) have been published. Whole-cell sensors, whole-cell biosensors, chemical sensors, integrated ...
Development of a novel method for in vivo determination of activation energy of glucose transport across S. cerevisiae cellular membranes. A biosensor-like approach
(Molecular Diversity Preservation International, 2009-03)
Whereas biosensors have been usually proposed as analytical tools, used to investigate the surrounding media pursuing an analytical answer, we have used a biosensor-like device to characterize the microbial cells immobilized ...
Fabrication of a novel enzymatic electrochemical biosensor for determination of tyrosine in some food samples
(Elsevier Science, 2018-06)
