Fabrication of an Amperometric Flow-Injection Microfluidic Biosensor Based on Laccase for In Situ Determination of Phenolic Compounds

Figure 5

Stability of the microfluidic biosensor. Measurements made each 24 h for 10 days using 0.1 M acetate buffer as the running buffer and 50 μM ABTS in acetate buffer 0.1 M (pH 5.0.) as the analyte solution for detection. Error bars describe the standard deviation of the three replicates.
