Figure 5

Amperometric response of NEGS with different conc. of glucose added in 0.1 M NaOH (pH 13) with 30 s of intervals. NEGS show no current response upon addition of different interference such as uric acid (UA), ascorbic acid (AA), Dopamine (DA) at a concentration of 50 μM of each, while a linear current response with varying glucose concentrations were clearly observed (inset calibration graph of current response vs. glucose concentration).
