A microporous anionic metal–organic framework for a highly selective and sensitive electrochemical sensor of Cu2+ ions.

We first reported an anionic metal–organic framework for electrode material for the electrochemical detection of Cu2+. The modified electrode shows an excellent selectivity, high stability and sensitivity, wide linear range and lower detection limit. This strategy for generating new electrode materials will be useful for preparing new sensors and reporters for biological systems. [ABSTRACT FROM AUTHOR]
