NAE (
Bai et al., 2008
), (d) binding of 400 mg/dl glucose in solution (hematocrit adjusted) to
40% FAD-GDH (flavin adenine dinucleotide-dependent glucose dehydrogenase) that was
screen-printed on a biosensor strip, (e) binding of blood glucose and urine glucose in postmeal
testing to a urine glucose meter (
Miyashita et al., 2009
), and (f) binding of 6 mMglucose in solu-
tion to screen-printed WB CoPC (cobalt phthalocyanine) (electrocatalyst) microband biosensor
(Pemberton et al., 2008).
Figure 7.1a-c
shows the binding and dissociation of 1 mM glucose in solution (using CV) to
Nf (Nafion)-CNTs-Cu(CU-CNT-GCE) (Kang et al., 2007). The influence of repeat runs in
chronological order, a,b, and c was analyzed by these authors. They have recently developed a
sensitive nonenzymatic glucose sensor in alkaline media with a copper nanocluster /multiwall
nanotube-modified GCE.

Binding of 1 mM glucose in solution (using CV, cyclic voltametry) to Nf (Nafion)-CNTs
