Journal ArticleDOI
Determination of thickness, dielectric constant of thiol films, and kinetics of adsorption using surface plasmon resonance.
TL;DR: The kinetic studies of the film formation in ethanol solution indicated that the self-assembled monolayer is formed in a two-step adsorption process, and this unpublished route was applied on the basis of a model where many molecules are adsorbed at an initial step and then can be desorbed and/or rearranged to form a perfect monolayers.
Journal ArticleDOI
Amperometric sensor for nitrite using a glassy carbon electrode modified with alternating layers of iron(III) tetra-(N-methyl-4-pyridyl)-porphyrin and cobalt(II) tetrasulfonated phthalocyanine.
Wilney de Jesus Rodrigues Santos,Aline L. Sousa,Rita de Cássia Silva Luz,Flavio Santos Damos,Lauro T. Kubota,Auro Atsushi Tanaka,Sônia M.C.N. Tanaka +6 more
TL;DR: The development of a highly sensitive amperometric sensor for nitrite using a glassy carbon electrode modified with alternated layers of iron(III) tetra-(N-methyl-4-pyridyl)-porphyrin and cobalt(II) tetrasulfonated phthalocyanine and the sensor was found to be tolerant against these ions.
Journal ArticleDOI
Voltammetric determination of 4-nitrophenol at a lithium tetracyanoethylenide (LiTCNE) modified glassy carbon electrode.
Rita de Cássia Silva Luz,Flavio Santos Damos,Adriano Bof de Oliveira,Johannes Beck,Lauro T. Kubota +4 more
TL;DR: The reduction of 4-nitrophenol (4-NP) has been carried out on a modified glassy carbon electrode using cyclic and differential pulse voltammetry (DPV) and the proposed sensor presented good repeatability and was applied for 4-NP determination in water samples.
Journal ArticleDOI
Dissolved oxygen sensor based on cobalt tetrasulphonated phthalocyanine immobilized in poly-l-lysine film onto glassy carbon electrode
TL;DR: In this paper, a simple and efficient method for determining dissolved oxygen at pH 6.5 is proposed using differential pulse voltammetry (DPV) and chronoamperometry.
Journal ArticleDOI
An amperometric sensor based on electrochemically triggered reaction : Redox-active Ar-NO/Ar-NHOH from 4-nitrophthalonitrile-modified electrode for the low voltage cysteine detection
Phabyanno Rodrigues Lima,Wilney de Jesus Rodrigues Santos,Rita de Cássia Silva Luz,Flavio Santos Damos,Adriano Bof de Oliveira,Marília O. F. Goulart,Lauro T. Kubota +6 more
TL;DR: In this article, the authors describe the development of a highly sensitive amperometric sensor based on a simple and efficient carbon paste electrode modified with a new redox mediator, 4-nitrophthalonitrile, toward detection of cysteine (CySH) in neutral medium at an applied potential of 0.33 V vs. Ag/AgCl.
