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. ...
An electrochemical biosensor for the detection of Mycobacterium tuberculosis DNA from sputum and urine samples
(Public Library of Science, 2020)
Tuberculosis (TB) is a major global public health problem with high mortality and morbidity. In low-middle income countries (LMIC) a large number of respiratory symptomatic cases that require TB screening per year demands ...
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)
In this work, fabrication of a novel and ultrasensitive electrochemical biosensor based on immobilization oftyrosine hydroxylase onto palladium-platinum bimetallic alloy nanoparticles/chitosan-1-ethyl-3-methylimidazolium ...
Development of a methodology for reversible chemical modification of silicon surfaces with application in nanomechanical biosensors
(Elsevier Advanced Technology, 2019-07)
Hypervalent tellurium compounds have a particular reactivity towards thiol compounds which are related to their biological properties. In this work, this property was assembled to tellurium-functionalized surfaces. These ...
A robust and practically free of charge intermittent use glucose biosensor
(Elsevier Science Sa, 2017-10)
In the past decades, great effort has been put in finding new electrode surface modifiers and enzyme immobilizer agents that prevent the enzyme leakage, minimize the effect of interfering species, retain the enzyme ...
Transduction methods used on biosensors: amperometry and fluorescenceMétodos de transducción usados en biosensores: amperometría y fluorescencia
(Universidad de Antioquia, Facultad de IngenieríaGrupo de Manejo Eficiente de la Energía (GIMEL)Medellín, Colombia, 2017)
Avidin and glucose oxidase-non-covalently functionalized multi-walled carbon nanotubes: A new analytical tool for building a bienzymatic glucose biosensor
(Wiley VCH Verlag, 2019-05)
We report an innovative supramolecular architecture for bienzymatic glucose biosensing based on the non-covalently functionalization of multi-walled carbon nanotubes (MWCNTs) with two proteins, glucose oxidase (GOx) (to ...
