Cyclic voltammograms of (a) Mfp3 fast and slow in pH 2 acetic acid solution; (b) Mfp3 fast and slow in pH 7.5 phosphate buffer. At pH 7.5, before measurement, Mfp3 fast and slow solutions were dropped onto the working electrode surface, and dried at the ambient temperature. The working electrode was then immersed in 0.1 M phosphate buffer for further measurement.
