A new Cu(I) probe (OBEP-CS1), bearing an alkyl-pyridinium moiety to get complete water solubility, was synthesized. Fluorescence titrations support copper binding and high selectivity in a water solution whereas formation of aggregates was excluded by DOSY experiments. The detection capability for intracellular Cu(I), especially localized in mitochondria, was demonstrated in differentiated neuroblastoma cells by confocal microscopy.

Abstract
A new Cu(I) probe (OBEP-CS1), bearing an alkyl-pyridinium moiety to get complete water solubility, was synthesized. Fluorescence titrations support copper binding and high selectivity in a water solution whereas formation of aggregates was excluded by DOSY experiments. The detection capability for intracellular Cu(I), especially localized in mitochondria, was demonstrated in differentiated neuroblastoma cells by confocal microscopy.File in questo prodotto:
