Progress with, and prospects for, metal complexes in cell imaging.

This article summarises the state of the art of metal complexes in cell imaging, particularly fluorescence microscopy, and presents prospects for the future development of this area. This article combines discussion of, and examples from, both the d- and f-block which have traditionally been considered separately, presenting the important classes of agents in each case, with a general description of their photophysical and cellular behaviour, and comparing and contrasting their properties and applications.
