Development of an operational substrate for ZapA, a metalloprotease secreted by the bacterium Proteus mirabilis
(Associação Brasileira de Divulgação Científica (ABRADIC), 2000-07-01)
The protease ZapA, secreted by Proteus mirabilis, has been considered to be a virulence factor of this opportunistic bacterium. The control of its expression requires the use of an appropriate methodology, which until now ...
Quenching of bathocuproine disulfonate fluorescence by Cu(I) as a basis for copper quantification
(Academic Press Inc Elsevier Science, 2002-08)
In this paper we report the up to now ignored fluorescence properties of the specific Cu(I)-chelator bathocuproine disulfonate and their application in assays of total copper and Cu(I). The method is based on the linear ...

Interaction between nitroxyl radicals and CdTe quantum dots: Determination of fluorescence-quenching mechanisms in aqueous solution
(2019)
The present work characterizes the optical properties of CdTe quantum dots (CdTe QDs) after interaction with nitroxyl radicals based on steady-state and time-resolved fluorescence spectroscopy studies. QDs of different ...
Derivatized silver nanoparticles as sensor for ultra-trace nitrate determination based on light scattering phenomenon
(Elsevier Science, 2009-01)
New silver nanoparticles coated with EDTA (EDTA-AgNPs) have been synthesized by citrate reduction method and characterized by UV-vis spectroscopy, molecular fluorescence and scanning electron microscopy (SEM). The derivatized ...
