Monitoring of Glucose in Beer Brewing by a Carbon Nanotubes Based Nylon Nanofibrous Biosensor

Figure 5

Chronoamperometric current responses of the biosensor with the GOX free or immobilized on the NFM/CNT, for increasing concentration of glucose. In the case of the GOX free in solution (NY CNT + free GOX), experimental points were fitted with Michaelis-Menten equation: , where )10⁻⁶ and . In the case of GOX immobilized on the NFM/CNT, the points were fitted with a Hill type equation: , where START = (−)10⁻⁷, END = ()10⁻⁵, = , and . In both cases, was 0.998. For the Michaelis-Menten fitting of NY CNT + imm GOX =  mM, =  μA (fitting was bad; therefore it is not shown).
