Abstract
⺠The optimum excitation wavelength for individual amino acid standard solutions is 390 nm. ⺠Except for isovaline the fluorescence maxima were found to be located consistently at 480 nm. ⺠Quenching ratio ranges from 1.4 in a 2-amino acid mixture to 2.2 in a 17-amino acid mixture. ⺠Isovaline cannot be detected below 10â5 M, while α-AIB is only detected above 10â6 M. ⺠Fluorescence spectroscopy provides fundamental specificity for the targeted molecules.
