Enantioselective cellular localisation of europium(III) coordination complexes

The selective mitochondrial localisation of the L enantiomer of three different emissive europium(III) complexes in NIH 3T3 and MCF7 cells contrasts with the behaviour of the (sic) enantiomer, for which a predominant lysosomal localisation was observed by confocal microscopy. In each case, cell uptake occurs via macropinocytosis.
