Abstract: Highlights: [•] PAMAM G4 dendrimer coordinates about 25 molecules of tryptophan. [•] PAMAM G4 dendrimer coordinates about 24 molecules of tyrosine. [•] Binding constant between PAMAM G4 and tryptophan equals about 130. [•] Solubility, dialysis, 1H NMR, NOESY and CD confirm the investigated interactions. [Copyright &y& Elsevier]
