Functional Nucleic Acid Based Biosensors for Transition Metal Ion Detection

  • Yunbo Luo


Transition metals account for a large portion of chemical elements in periodic table and are crucial for analysis. As important microelements, the content of zinc ion, copper ion and chromium ion is the key for human health, otherwise excess intake will do harm for metabolism. However, poisonous transition metal ions, such as mercury ion and cadmium ion, were paid much attention for their high toxicity even in low content. In this chapter, detection methods based on functional nucleic acids (FNAs) for five representative transition metal ions composed of zinc ion, copper ion, mercury ion, cadmium ion and chromium ion were summarized.
