[Eu2(LC3)3] is observed on the viability of several cancerous cell lines (MCF-7, HeLa, Jurkat, and 5D10). The cell imaging properties of the EuIII helicate are demonstrated for the HeLa cell line by luminescence microscopy. Bright EuIII emission is seen for helicate concentration>50 microM and after 20-30 min loading time. The helicatestains the cytoplasm and the permeation mechanism is likely to be
