Genetically encoded fluorescent sensors for measuring transition and heavy metals in biological systems.

abstract：:A broad range of biochemicals, from proteins to nucleic acids, function properly only when associated with a metal, usually a divalent cation. Not any divalent metal will do: these metals differ in their ionic radius, dissociation in water, ionization potential, and number of unpaired electrons in their outer shells, ...
