“…Indeed, the biosensor sensitivity varies between 380 and 450 nA mM À 1 mm À 2 within the first 10 days. The obtained results are in agreement with previous works based on immobilization of oxidases in chitosan (Wu et al, 2009;Tsai et al, 2007;Tangkuaram et al, 2007).…”

A potentiometrically tuned-glucose biosensor was fabricated using core-shell nanocomposite based on zinc oxide encapsulated chitosan-graft-poly(vinyl alcohol) (ZnO/CHIT-g-PVAL). The glucose oxidase (GOD) was immobilized onto ZnO/CHIT-g-PVAL coated indium-tin oxide (ITO) glass substrate. The electrostatic interaction between GOD and ZnO based core-shell nanocomposite provided the resulting tuned enzyme electrode (GOD/ZnO/CHIT-g-PVAL) with a high level of enzyme immobilization and excellent lifetime stability. The response studies were carried out as a function of GOD concentration with potentiometric measurement. The GOD/ZnO/CHIT-g-PVAL/ITO bioelectrode has showed a linear potential response to the glucose concentration ranging from 2 μM to 1.2 mM. The glucose biosensor exhibited a sensitivity of >0.04 V/M with a response time within three sec.

“…They are also used in modifying the glassy carbon electrode. Normally, a binder such as nafion or chitosan has been used for this purpose [Tsai et al, 2005[Tsai et al, , 2007Liaw et al, 2006]. The CNT paste electrodes were prepared by mixing CNTs with mineral oil.…”
