Journal ArticleDOI
Layer-by-Layer Self-Assembly of Glucose Oxidase with a Poly(allylamine)ferrocene Redox Mediator
TL;DR: In this article, a self-assembled structure of cationic poly(allylamine) modified by ferrocene (PAA-Fc) and anionic GOx was deposited electrostatically layer-by-layer on negatively charged alkanethiol-modified Au surfaces.
Journal ArticleDOI
Layer-by-layer self-assembly of glucose oxidase and Os(Bpy)2ClPyCH2NH-poly(Allylamine) bioelectrode
Ernesto J. Calvo,Roberto Etchenique,Lía I. Pietrasanta,Alejandro Wolosiuk,Claudia Danilowicz +4 more
TL;DR: The uptake of glucose oxidase (GOx) onto a polycationic redox polymer (PAA-Os)-modified surface, by adsorption from dilute aqueous GOx solutions, was followed by the quartz crystal microbalance (QCM) and shows double exponential kinetics.
Journal ArticleDOI
Infrared Spectroscopy Studies on Stability of Dimethyl Sulfoxide for Application in a Li–Air Battery
TL;DR: In situ infrared subtractive normalized Fourier transform infrared spectroscopy (SNIFTIRS) experiments performed simultaneously with the electroreduction of oxygen on gold and platinum cathodes in LiPF6 dimethyl sulfoxide (DMSO) electrolyte have shown that the solvent is stable with respect to nucleophilic attack by the electrogenerated superoxide radical anion as mentioned in this paper.
Journal ArticleDOI
Wired-enzyme core-shell Au nanoparticle biosensor.
Pablo Scodeller,Victoria Flexer,Rafael Szamocki,Ernesto J. Calvo,Nicolás G. Tognalli,Horacio Esteban Troiani,Alejandro Fainstein +6 more
TL;DR: A proof of concept extending the work done with planar surfaces to core-shell NPs as an advance in the design of glucose-responsive chemistry detected by SERS-like methods is presented.
Journal ArticleDOI
Layer-by-layer electrostatic deposition of biomolecules on surfaces for molecular recognition, redox mediation and signal generation.
TL;DR: Layer-by-layer supramolecular structures composed of alternate layers of negatively charged enzymes and cationic redox polyelectrolyte have been assembled and differences in GOx electrical wiring efficiency have been detected with the different assembling strategies.
