Penicillamine determination using a tyrosinase micro-rotating biosensor
(Elsevier Science, 2006-11)
Tyrosinase [EC 1.14.18.1], immobilized on a rotating disk, catalyzed the oxidation of catechols to o-benzoquinone, whose back electrochemical reduction was detected on glassy carbon electrode surface at -150 mV versus ...
Azospirillum brasilense siderophores with antifungal activity against Colletotrichum acutatum
(Springer, 2011-04)
Anthracnose, caused by the fungus Colletotrichum acutatum is one of the most important diseases in strawberry crop. Due to environmental pollution and resistance produced by chemical fungicides, nowadays biological control ...
Experimental and Theoretical Study of the Stability of the Complex Fisetin–Cu(II) and A Comparative Study of Free Ligand and Complex Interaction with Molecular Singlet Oxygen
(Wiley Blackwell Publishing, Inc, 2020-07)
In this work, the flavonol fisetin was selected in order to study its reactivity against Cu(II), a metal ion of interest in biological media and industry. The stoichiometry and apparent formation constant of the complex ...
Absorption mechanism of dopamine/DOPAC-modified TiO2 nanoparticles by time-dependent density functional theory calculations
(Elsevier Ltd, 2021-03)
Donor-modified TiO2 nanoparticles are interesting hybrid systems shifting the absorption edge of this semiconductor from the ultra-violet to the visible or infrared light spectrum, which is a benefit for several applications ...
Screening for cystic fibrosis via a magnetic and microfluidic immunoassay format with electrochemical detection using a copper nanoparticle-modified gold electrode
(Springer Wien, 2016-10)
This article describes a microfluidic electrochemical immunoassay that features two strategies, viz. (a), the incorporation of magnetic nanoparticles (MNPs) into the central microfluidic channel and acting as a bioaffinity ...
Copper alters the physiology of tomato rhizospheric isolates of Papiliotrema laurentii
(Elsevier Science, 2019-01)
In horticulture copper sulphate is utilized for the inhibition of phytopathogenic fungi. However, copper tends to accumulate in soil with a concomitant effect on soil quality and microbial diversity. As part of the biological ...
Exploring the chemical space of 1,2,3-triazolyl triclosan analogs for discovery of new antileishmanial chemotherapeutic agents
(Royal Society of Chemistry, 2021-01)
Triclosan and isoniazid are known antitubercular compounds that have proven to be also active againstLeishmaniaparasites. On these grounds, a collection of 37 diverse 1,2,3-triazoles based on the antitubercular molecules ...
Lasiodiplodia gilanensis used as model for understanding the pathogenicity of Botryosphaeriaceae
(Firenze University Press, 2019)
Lasiodiplodia spp. cause degenerative diseases, dieback and plant death in a wide range of woody plants. To understand the fungal behavior of the genus we are using Lasiodiplodia gilanensis as a model. A transcriptional ...
Modified paramagnetic beads in a microfluidic system for the determination of ethinylestradiol (EE2) in river water samples
(Elsevier Advanced Technology, 2010-03-02)
In this work, we have developed and characterized a novel microfluidic immunoassay methodology for rapid and sensitive quantification of ethinylestradiol (EE2) in river water samples. The detection of EE2 was carried out ...
Complex numbers-partial least-squares applied to the treatment of electrochemical impedance spectroscopy data
(Elsevier Science, 2019-11)
This work investigated the application of partial least-squares regression of complex numbers on multivariate data obtained by electrochemical impedance spectroscopy (EIS). The use of complex numbers–PLS was evaluated in ...
