Chemosensors Based on Metal-Dye Complexes for Bioanalytes

Multicomponent chemosensors were prepared by mixing the rhodium(III) complex [(η5-C5Me5)RhCl 2]2, nickel(II) chloride and/or copper(II) chloride with commercially available dyes in buffered aqueous solution. The sensors were used to detect various biomolec ...

Cross-Reactive Sensor Arrays for the Detection of Peptides in Aqueous Solution by Fluorescence Spectroscopy

Kay Severin, Sébastien Rochat, Friederike Gundula Marie Zaubitzer, Jie Gao

A simple but powerful method for the sensing of peptides in aqueous solution has been developed. The transition-metal complexes [PdCl2(en)], [{RhCl2Cp*}2], and [{RuCl2(p-cymene)} 2] were combined with six different fluorescent dyes to build a cross-reactiv ...

Sensing with Dynamic Combinatorial Libraries of Metal-Dye Complexes: The Advantage of Time-Resolved Measurements

Kay Severin, Friederike Gundula Marie Zaubitzer

A dynamic combinatorial library of metal–dye complexes was obtained by reacting aqueous solutions of the dyes Methyl Calcein Blue, Arsenazo I, and Xylenol Orange with CuCl2 and NiCl2. The mixture gave a characteristic UV-Vis response upon addition of the p ...

Cp*Rh-Based Indicator Displacement Assays for the Identification of Amino Sugars and Aminoglycosides

Kay Severin, Andrey Buryak, Friederike Gundula Marie Zaubitzer

Indicator displacement assays based on the organometallic complex [Cp*RhCl2]2 and the dye gallocyanine have been used to sense aminosugars and aminoglycosides in buffered aqueous solution by UV-Vis spectroscopy. The data of three assays at pH 7.0, 8.0 and ...
