Neutral Red
Neutral red (3-Amino-7-dimethylamino-2-methylphenazine hydrochloride) is a phenazine-based dye which has an suitable redox-potential to function as an electron-shuttle from the electrode to the cells.
Figure 1: Chemical structure of the triphenylmethane dye neutral red.
Bromphenol Blue
Bromphenolblue is a triarylmethane dye that is similar to neutral red and also capable to function as mediator.

Cytochromes
Cytochromes are proteins containing a heme group. They are primarly responsible for the electron transport in the respiratory chain.References
