Affinity ligand biosensing liquid membranes
Affinity ligand biosensing liquid membranes
The technique of d-c polarography was developed for a water/1,2 dichloroethane system and it was shown that analysis of results can follow in an analogous manner to those obtained at a dropping mercury electrode.
The suitability of the triazine dyes Cibacron blue F3GA and Procion blue Mx-R as biosensing ligands in a liquid-liquid system was investigated using cyclic voltammetry and inter facial tension. The latter made use of the process of video image processing and demonstrated a strong adsorption/desorption phenomenon of the dyes. This phenomenon is explained in terms of the ionization of the NH. group of the antracene part of the dyes forming a zwitterion which is strongly adsorbed. It is proposed that only the antkrooene part of the dye molecule is in contact with the aqueous phase by virtue of its polarity.

Abstract
The technique of d-c polarography was developed for a water/1,2 dichloroethane system and it was shown that analysis of results can follow in an analogous manner to those obtained at a dropping mercury electrode.
The suitability of the triazine dyes Cibacron blue F3GA and Procion blue Mx-R as biosensing ligands in a liquid-liquid system was investigated using cyclic voltammetry and inter facial tension. The latter made use of the process of video image processing and demonstrated a strong adsorption/desorption phenomenon of the dyes. This phenomenon is explained in terms of the ionization of the NH. group of the antracene part of the dyes forming a zwitterion which is strongly adsorbed. It is proposed that only the antkrooene part of the dye molecule is in contact with the aqueous phase by virtue of its polarity.
