Amino acids play essential role for humans. We studied the dielectric properties of the basic aliphatic amino acids and polar positive amino acids in solutions of different concentrations. The enhanced to a number of measurement frequencies high-Q single microwave whispering gallery-mode (WGM) quartz dielectric resonator based technique was applied. The technique allows liquids investigation of micro- to nano- liter volumes filled in microfluidic channel on six discrete frequencies in 30-40 GHz range. The dependencies of the complex permittivity on the molar mass show almost linear behavior for aliphatic amino acids for different concentrations. The investigation results are in good agreement with the calculated data obtained by Cole-Cole equation. |
