Journal ArticleDOI
The use of luminescent quantum dots for optical sensing
TL;DR: In this paper, the authors review progress in exploiting the attractive luminescent properties of quantum dot nanocrystals in designing novel probes for chemical and biochemical optical sensing, and present a survey of the state of the art.
Journal ArticleDOI
Isotope dilution analysis for elemental speciation: a tutorial review
Pablo Rodríguez-González,Juan Manuel Marchante-Gayón,J. Ignacio García Alonso,Alfredo Sanz-Medel +3 more
TL;DR: In this article, the authors describe in some depth one of the most accurate approaches developed so far for such purpose: the application of isotope dilution analysis to quantitative elemental speciation.
Journal ArticleDOI
Photoactivated luminescent CdSe quantum dots as sensitive cyanide probes in aqueous solutions.
Wei Jun Jin,María Teresa Fernández-Argüelles,José M. Costa-Fernández,Rosario Pereiro,Alfredo Sanz-Medel +4 more
TL;DR: Water-soluble luminescent CdSe quantum dots surface-modified with 2-mercaptoethane sulfonate were synthesized for the selective determination of free cyanide in aqueous solution with high sensitivity via analyte-induced changes in their photoluminescence after photoactivation.
Journal ArticleDOI
Dye-surfactant interactions: a review
TL;DR: The present state of knowledge of the mechanisms of dye-surfactant interactions for "normal" aqueous micelles is surveyed and some discussion along these lines on related systems (reverse micells, vesicles, polyelectrolytes) is included.
Journal ArticleDOI
Surface-modified CdSe quantum dots for the sensitive and selective determination of Cu(II) in aqueous solutions by luminescent measurements
María Teresa Fernández-Argüelles,Wei Jun Jin,José M. Costa-Fernández,Rosario Pereiro,Alfredo Sanz-Medel +4 more
TL;DR: In this article, the use of water-soluble luminescent CdSe quantum dots (QDs), whose surface was modified either with 2-mercaptoethane sulphonic acid or with 2mercaptosophane acyclic acid, was investigated for the sensitive and selective determination of copper(II) ions in aqueous solutions.
