A colorimetric sensing ensemble was prepared by mixing readily prepared adenosine triphosphate (ATP)stabilized AuNPs with Cu 2+ -phenanthroline complexes. The sensing mechanism of the ensemble was examined by UV-vis spectrometry and transmission electron microscopy. The studies showed that the Cu 2+
