5">Nonadiyne protects Si against oxidation in aqueous media but makes it passivated.
- •
Attaching AuNPs to amine-terminated Si “switches on” the electron transfer.
- •
5">AuNPs appear to catalyze the formation of SiOx before and during cyclic voltammetry.
- •
AuNPs cause oxidation of Si, but surfaces are suitable for single use applications.
