Sensing of peptide hormones with dynamic combinatorial libraries of metal–dye complexes: the advantage of time-resolved measurements?

Organic & Biomolecular Chemistry Pub Date: 2009-09-03 DOI: 10.1039/B912400D

Abstract

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 peptide hormones angiotensin I and angiotensin II. This allowed distinguishing pure samples of peptide hormones from mixtures. The discriminatory power of the sensor was enhanced when the several UV/Vis measurements were performed during the equilibration process of the library.
