Highly Sensitive and selective glucose biosensing at carbon paste electrodes modified with electrogenerated magnetite nanoparticles and glucose oxidase
(Wiley VCH Verlag, 2010-07)
This work reports the advantages of carbon paste electrodes modified with electrogenerated magnetite nanoparticles. The nanoparticles present catalytic activity towards hydrogen peroxide reduction. The incorporation of ...
Simultaneous co-immobilization of three enzymes onto a modified glassy carbon electrode to fabricate a high-performance amperometric biosensor for determination of total cholesterol
(Elsevier Science, 2018-12)
In this work, we have fabricated a novel amperometric cholesterol (CHO) biosensor because of the importance of determination of CHO levels in blood which is an important parameter for diagnosis and prevention of disease. ...
Nanoarchitectures based on multi-walled carbon nanotubes non-covalently functionalized with Concanavalin A: A new building-block with supramolecular recognition properties for the development of electrochemical biosensors
(Elsevier Science SA, 2019-08)
We propose an innovative nanoarchitecture for the development of electrochemical biosensors based on the non-covalent functionalization of multi-walled carbon nanotubes (MWCNTs) with the lectin Concanavalin A (ConA) and ...
A sensitive whole-cell biosensor for the simultaneous detection of a broad-spectrum of toxic heavy metal ions
(Royal Society of Chemistry, 2015-04)
Bacterial biosensors are simple, cost-effective and efficient analytical tools for detecting bioavailable heavy metals in the environment. This work presents the design, construction and calibration of a novel whole-cell ...
Fabrication of a novel impedimetric biosensor for label free detection of DNA damage induced by doxorubicin
(Elsevier Science, 2019-02)
In this work, a novel impedimetric biosensor has been fabricated for detection of DNA damage induced by doxorubicin (DX). Cytochrome P450 reductase (CPR) is required for electron transfer from nicotinamide adenine dinucleotide ...
Mucin and carbon nanotube-based biosensor for detection of glucose in human plasma
(Academic Press Inc Elsevier Science, 2018-06)
This work reports an amperometric enzyme-electrode prepared with glucose oxidase, which have been immobilized by a cross-linking step with glutaraldehyde in a mixture containing albumin and a novel carbon nanotubes-mucin ...
Development of an enzymatic biosensor to determine eugenol in dental samples
(Elsevier Science, 2020-04)
A GCE/CRGO-βCD′s/ADA-SPE/AuNPs biosensor was successfully developed to determine eugenol in dental samples. The optimal conditions to construct the biosensor were obtained from an experimental design based on the response ...
