Abstract

A highly specific interaction between a metal-deficient metalloenzyme and metal ion has been utilized in the selective detection of the metal ion by surface plasmon resonance spectroscopy (SPRS). The use of SPRS and Cu-demetallated superoxide dismutase (E,Zn-SOD1) as a sensing actuator allows one to selectively and in situ detect Cu2+ without any interference that other spectroscopic methods may have.
