The complex dielectric permittivity spectra, e\*(m), of aqueous glycine solutions at 25 8C were determined in the frequency range of 0.1Vm/ GHzV89 using TDR and wave-guide interferometry. The concentration range covered amino acid mole fractions of 0VXV0.05, corresponding to molar concentrations of
The complex dielectric constant of collagen in aqueous solutions (polymer concentration, C, = 0.02-0.2%) was measured a t 10Β°C in the frequency range from 3 Hz to 30 kHz. The loss peak for C, = 0.02% is located a t 90 Hz and the dielectric relaxation time rn is estimated to be 1.8 f 0.3 msec. The TL
