Colorimetric and fluorometric detection of copper ion (Cu 2+) has attracted much attention because of the biological, environmental and medical significance of the Cu 2+ion.
Colorimetric and fluorometric detection of copper ion (Cu 2+) has attracted much attention due to the biological, environmental and medical significance of the Cu 2+ion. Colorimetric and fluorescent detection of metal ions have proven to be powerful methods due to their simplicity, cost effectiveness, high detection limit and applicability to bioimaging. This review will consolidate selective and sensitive Cu 2+ion detection achieved by various receptor types in the years between 2013 to 2015.
