abstract = {Graphene has numerous potential applications in ultrathin
electronics. There an electrode should function in contact
with fluids and under mechanical stress; therefore, its
stability is specifically of concern. Here, we explored a
custom-made quartz crystal microbalance (QCM) sensor covered
with wet-transferred large-scale monolayer graphene for
investigation of an electrode behavior. Monolayer graphene
was found to be stable on an oscillating substrate in
contact with air and liquid. Under the liquid flow and
simultaneously applied electrochemical potential, we managed
to induce graphene oxidation, impact of which was observed
on a quartz crystal microbalance monitoring and Raman
spectra. Applied potentials of 1 V and higher (vs. Ag/AgCl
reference electrode) caused graphene oxidation which led to
loss of the layer integrity and erosion of the material.},
