A gold(I)-pyrazolato complex has been designed as a luminescent probe for cysteine (Cys). Spectroscopy and microscopy experiments revealed that the complex would disintegrate in the presence of Cys to form gold-Cys fluorescent nanoparticles, and was found to enhance Cys to form rose-like microspheres in solution.
