Substituent-dependent fluorescent sensors for zinc ions based on carboxamidoquinoline.
A series of carboxamidoquinoline-based fluorescent sensors (the AQZ family) were synthesized and characterized. The AQZ family members were highly soluble in water and showed good selectivity for Zn(2+)via enhanced fluorescence in aqueous buffer solution. Fluorescence signals could be tuned from dual-wavelength ratiometric changes to changes in the intensity of a single wavelength upon binding ...
متن کاملZinc Oxide-Based Self-Powered Potentiometric Chemical Sensors for Biomolecules and Metal Ions
Advances in the miniaturization and portability of the chemical sensing devices have always been hindered by the external power supply problem, which has focused new interest in the fabrication of self-powered sensing devices for disease diagnosis and the monitoring of analytes. This review describes the fabrication of ZnO nanomaterial-based sensors synthesized on different conducting substrate...
متن کاملAntibody-based sensors for heavy metal ions.
Competitive immunoassays for Cd(II), Co(II), Pb(II) and U(VI) were developed using identical reagents in two different assay formats, a competitive microwell format and an immunosensor format with the KinExA 3000. Four different monoclonal antibodies specific for complexes of EDTA-Cd(II), DTPA-Co(II), 2,9-dicarboxyl-1,10-phenanthroline-U(VI), or cyclohexyl-DTPA-Pb(II) were incubated with the ap...
متن کاملSelective binding of zinc ions
The relative binding affinity of Zn2+ to several glycosaminoglycans was determined by gel-filtration chromatography. Binding was observed only between Zn2+ and heparin. No binding was observed between Zn2+ and chondroitin 4-sulphate, chondroitin 6-sulphate, dermatan sulphate or hyaluronic acid. All of the glycosaminoglycans contained carboxy groups, but only heparin bound Zn2+. This observation...
متن کاملThe effect of zinc ions
The fertilization rate of mouse gametes in a Krebs-Ringer bicarbonate medium was 60%. The rate fell to 0% when 250 \g=m\M-ZnCl2 was added, but MgCl2, CaCl2, MnCl2, FeCl2 and CuCl2 (each at 250 \g=m\M)had no effect. The inhibitory effect of Zn2+ was not evident if the spermatozoa or eggs were preincubated with Zn2+ or if previously capacitated spermatozoa were used. The Zn2+ is thought to act by...
