CYANIDE DETERMINATION WITH A MODIFIED NINHYDRIN REAGENT USING N-ACETYL CYSTEINE IN THE PRESENCE OF HEAVY METAL IONS
(Sociedad Chilena de Química, 2010)
A single serine residue determines selectivity to monovalent metal ions in metalloregulators of the MerR family
(American Society for Microbiology, 2015-05)
MerR metalloregulators alleviate toxicity caused by an excess of metal ions, such as copper, zinc, mercury, lead, cadmium, silver, or gold, by triggering the expression of specific efflux or detoxification systems upon ...
Electrochemical sensor based on Sb nanoparticles/reduced graphene oxide for heavy metal determination
(2020-01-01)
This paper presents the characterisation and for the first time the application of a nanocomposite based on reduced graphene oxide (rGO) modified with antimony nanoparticles (SbNPs) in the stripping analysis of Cd2+, Pb2+, ...
Evaluation of a reduced graphene oxide-Sb nanoparticles electrochemical sensor for the detection of cadmium and lead in chamomile tea
(2020-09-01)
The development of electroanalytical sensors for heavy metals detection in complex matrices holds great interest. Herein, a sensor based on a reduced graphene oxide (rGO) modified with antimony nanoparticles (Sb) was ...
Ultrathin films of lignins as a potential transducer in sensing applications involving heavy metal ions
(Elsevier B.V. Sa, 2008-02-22)
Lignins extracted from sugar cane bagasse using different alcohols in the organosolv-CO(2) supercritical pulping process have been applied in the fabrication of ultrathin films through the Langmuir-Blodgett technique. ...

Nanocomposites based on LbL films of polyaniline and sodium montmorillonite clay
(Elsevier B.V., 2014-11-01)
Layer-by-layer (LbL) films were fabricated with alternating layers of montmorillonite (Na+-MMT) and either polyaniline emeraldine salt (PAni-ES) or polyethyleneimine (PEI). Molecular-level interactions between the film ...
