Abstract
A metal ion detection and quantification system in which the displacement of a radioactive isotope from a material that binds both the metal ion of interest and the radioactive isotope. The material in question binds the radioactive isotope with less force than the isotope of interest. The extent of release of the radioactive isotope is used to determine the concentration of the metal ion of interest. In one embodiment of the invention, the material used to bind the metal ion and radioactive ion is a protein of the metallothionein class of proteins.
