A selective ATP chromogenic sensor for use in an indicator displacement assay

We synthesized a dinuclear Zn2+ complex that is useful as a sensor for ATP in a DMSO/H2O (1:9, v/v) solvent system via a simple indicator displacement assay (IDA). This chromogenic sensor method can be used to analyze 0.1-2.0 μM of ATP with no interference from ADP or AMP.
