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 ...
Electrochemical Sensors Based on Poly(O-Aminophenol)
(Scholars Scitech Research Organization, 2017-12)
Interesting practical uses of nonconducting poly(o-aminophenol) (POAP) films in the fields of bioelectrochemistry are discussed in this paper. Particular emphasis is given to the effects of applied potential, solution pH ...
Glassy carbon electrodes modified with multiwall carbon nanotubes dispersed in polylysine
(Wiley VCH Verlag, 2008-08)
We report the analytical performance of glassy carbon electrodes (GCE) modified with a dispersion of multi-wall carbon nanotubes (MWCNT) in polylysine (Plys) (GCE/MWCNT-Plys). The resulting electrodes show an excellent ...

Glucose biosensor based on multisegment nanowires exhibiting reversible magnetic control
(Elsevier B.V., 2014-11-01)
We describe the amperometric detection of glucose using oriented nanowires with magnetic switching of the bioelectrochemical process. The fabrication process of the nanowires was prepared through controlled nucleation and ...
Real-time measurement of glucose using chrono-impedance technique on a second generation biosensor
(Elsevier Advanced Technology, 2011-11)
Chrono-impedance technique (CIT) was implemented as a new transduction method for real time measurement of glucose in a biosensor system based in carbon paste (CP)/Ferrocene (FC)/glucose oxidase (GOx). The system presents ...
