Une nouvelle molécule fluorescente amphiphile à base d'anthracène liée à la pyridine facilement accessible est signalée comme la sonde unique pour la détection systématique et rapide de plusieurs ions métalliques au niveau ppb. Parmi plusieurs ions métalliques, la trempe en intensité de fluorescence du fluorophore était remarquable pour les ions métalliques Pd2+, Fe3+, Sn2+, Bi3+ et Al3+ dans le milieu 1,4-dioxane où Al3+ a été immédiatement identifié avec sa trempe à 50 %. L'ajout de la solution Fe3+ à la sonde a produit un décalage bleu distinct dans le spectre d'absorption sous spectroscopie UV-Visible. En outre, la sonde pourrait discriminer le reste des trois ions métalliques Pd2+, Sn2+ et Bi3+ en utilisant des assemblages LED tensioactifs comme les micelles et les niosomes. Dans les micelles anioniques (SDS), la sonde peut détecter sélectivement l'ion Bi3+. La différenciation entre Pd2+ et Sn2+ a été obtenue en enregistrant leurs spectres d'émission dans des niosomes Tween 20 et span-80 neutres, où la sonde a montré une extinction spectaculaire uniquement avec Pd2+. Enfin, le capteur a été utilisé avec succès pour capturer l'image des cellules du cancer du col utérin (HeLa) facilitant la détection intracellulaire de Pd2+.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -An easily accessible pyridine-linked anthracene-based new amphiphilic fluorescent molecule is reported as the single probe for systematic and rapid sensing of multiple metal ions at ppb level. Among several metal ions, the quenching in fluorescence intensity of the fluorophore was remarkable for Pd2+, Fe3+, Sn2+, Bi3+ and Al3+ metal ions in the 1,4-dioxane medium where Al3+ was straightaway identified with its 50% quenching. The addition of Fe3+solution to the probe produced a distinct blue shift in the absorption spectrum under UV-Visible spectroscopy. Further, the probe could discriminate rest of the three metal ions Pd2+, Sn2+ and Bi3+ by using surfactant led assemblies like micelles and niosomes. In anionic micelles (SDS), the probe could selectively detect Bi3+ ion. The differentiation between Pd2+ and Sn2+ was achieved by recording their emission spectra in neutral Tween 20 micelles and span-80 niosomes, where the probe showed dramatic quenching only with Pd2+. Finally, the sensor was successfully utilized to capture the image of cervical cancer (HeLa) cells facilitating intracellular detection of Pd2+. 52 pp. Englisch. N° de réf. du vendeur 9786133999442
