A nanocontainer that releases a fluorescence sensor for cadmium ions in water and its biological applications

Abstract

A single-molecule functionalized “nanocontainer” NC-FQDIPA can release a fluorescence sensor to recognize cadmium ions in water with a relatively strong fluorescence intensity and improved selectivity. This device demonstrates sensitive detection of Cd2+ on the membrane of HeLa cells, which indicates the potential applications of this detection method in biological systems.
