Electrochemical Sensor for Determination of Metallothionein as Biomarker

Metallothionein (MT) belongs to group of intracellular, high molecular and cysteine-rich proteins. Thanks to its high affinity to heavy metals, the main function of this protein is maintaining homeostasis and detoxification of heavy metals. Thus, this protein is thought to be biomarker of heavy metal pollution. The adsorptive transfer stripping technique in connection with differential pulse voltammetry - Brdicka reaction has been utilized suggesting of sensor for determining of this biomarker.
