Tryptophan-based fluorescent sensor for selective Cu2+ detection in aqueous media and its docking study for anticancer effects

Results in Chemistry
In this study, an efficient copper (II) chemosensor was introduced. This chemosensor had a different response in fluorescent spectra, and the interaction between Cu2+ and tryptophan hydrazide (TH) was substantiated as a static quencher.
