ferrocenium (plural ferroceniums)
(organic chemistry) The univalent cation [Fe(C5H5)2] obtained by the oxidation of ferrocene
Ferrocene can itself be oxidized to the ferrocenium cation (Fc + ); the ferrocene/ferrocenium couple is often used as a reference in electrochemistry. Source: Internet
Potential applications The ferrocene/ ferrocenium biosensor has been discussed for determination the levels of glucose in a sample electrochemically through a series of connected redox cycles. Source: Internet
