Glucose biosensor based on multisegment nanowires exhibiting reversible magnetic control
(Elsevier B.V., 2015)
Modification of composites of block copolymers-gold nanoparticles with enzymes and their characterization by electrochemical techniques
(SPRINGER, 2011)
In this work, the poly(styrene-vynil pyridine) block copolymer was used as a porous pattern to study the electrodeposition of gold inside the pores, as a new method to obtain gold nanoparticles. The porous pattern left by ...
Layer-by-layer assembly of functionalized reduced graphene oxide for direct electrochemistry and glucose detection
(2016-11-01)
We report an electrochemical glucose biosensor made with layer-by-layer (LbL) films of functionalized reduced graphene oxide (rGO) and glucose oxidase (GOx). The LbL assembly using positively and negatively charged rGO ...
Improving the performance of a glucose biosensor using an ionic liquid for enzyme immobilization. On the chemical interaction between the biomolecule, the ionic liquid and the cross-linking agent
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
The effect of the room temperature ionic liquid (1-butyl-2,3-dimethylimidazolium tetrafluoroborate ([BMMI][BF4])) on the immobilization of glucose oxidase (GOx) was studied. The electrochemical performance of biosensors ...
Desarrollo de un biosensor de glucosa no enzimático basado en ZnO depositado por sputtering
(2019-02-13)
RESUMEN: En este trabajo de investigación, se depositaron películas delgadas de ZnO mediante la técnica de erosión catódica por corriente directa pulsada para su aplicación en el desarrollo de biosensores de glucosa no ...
Reduced graphene oxide obtained by gamma radiation to produce screen printed glucose biosensor
(International Atomic Energy Agency (IAEA), 2023)
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 ...
Desenvolvimento de biossensores utilizando nanotubos de carbono e nanopartículas de ouro
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2012-06-22)
First, a glassy carbon electrode modified with functionalized carbon nanotubes (CNTs) and glucose oxidase was proposed. Cyclic voltammetry of GOx immobilized onto the surface of CNTs showed a pair of well-defined redox ...
