Figure 5

Relative current responses of the Lac/Si/MWCNTs/SPE loading variable amount of MWCNTs to 60 μM DA in 0.10 M PBS (pH 5.0). Scan rate: 50 mV s-1. The cathodic currents are expressed as the percentage of the maximum response obtained at mass proportion of MWCNTs/carbon paste of 3:10. The mass proportion of MWCNTs/carbon paste (MWCNTs:carbon paste) in the process of screen-printing is 1:50, 1:10, 4:25, 1:5, 3:10, and 2:5, respectively.
