Nanostructured gold electrode

Tiefenauer et al. [35] used a nanostructured gold electrode with an interelectrode space of about 30 nm for an amperometric immunosensor. A hapten was immobilized in that space on Si02- In combination with ferrocene-or heme-modified antibodies, this concept can be used to increase the... 

In the same way, Sarapuu et al. [30] extended their previous works studying the ORR on nanostructured gold electrodes both in acidic (0.5 M H2SO4) and alkaline...

A colloidal suspension of nanostructured PBI-graphene sheets was used to modify a gold electrode to form a three-dimensional electrode with a sensitivity to hydrogen peroxide [25]. The positively charged nanostructured PBI separate the graphene sheets and keep them suspended in aqueous solution. This so fabricated electrode exhibits superior sensitivity toward hydrogen peroxide.
