Versatile polymeric membrane ion-selective electrodes based on cellulose triacetate
Abstract
-ISE membrane can be simply obtained by alkaline hydrolysis of the electrode. The hydrolyzed surface of the obtained membrane can further be activated with carbonyldiimidazole (CDI) for the direct immobilization of the functionalized agent, polysaccharide chitosan, on the surface of the membranes. In addition, an enzyme, butyrylcholinesterase, can also be immobilized onto the ISE surface through a similar CDI reaction, which provides great potential for fabrication of new potentiometric biosensors. It will be shown that CTA can be used as a powerful membrane matrix alternative to the classical PVC matrix for fabrication of polymeric membrane optical and electrochemical sensors in clinical applications.
