Conductometric chemosensors based on calixarenes for determination of amines and amino acids

Résumé

Thin-film interdigitated planar electrodes based on calixarenes have been used for the development of conductometric amine and amino acid chemosensors. The optimal values of pH, buffer capacity and ionic strength have been determined. Operational stability, storage stability and selectivity of the developed conductometric biosensor have also been analyzed. The optimum pH values for amine sorption were observed at pH = 5.5 for the calixarene derivatives. The experimental results show that C-benzylresorcinolcalixarene exhibited a better affinity than the other macrocycles toward amine species.
