Fabrication of a glucose sensor based on a novel nanocomposite electrode
The direct electrocatalytic oxidation of glucose in alkaline medium at nanoscale nickel hydroxide modified carbon ionic liquid electrode (CILE) has been investigated. Enzyme free electro-oxidation of glucose have greatly been enhanced at nanoscale Ni(OH) 2 as a result of electrocatalytic effect of N...

3). The nanoscale nickel hydroxide modified electrode is relatively insensitive to electroactive interfering species such as ascorbic acid (AA), and uric acid (UA) which are commonly found in blood samples. Long-term stability, high sensitivity and selectivity as well as good reproducibility and high resistivity towards electrode fouling resulted in an ideal inexpensive amperometric glucose biosensor applicable for complex matrices. |
