  text: The transport properties of nanofluidic channels are usually studied under
    constant (DC) voltage or pressure driving. However, the frequency response under
    sinusoidal (AC) drivings offers rich insights into the time-dependent transport
    mechanisms. Inspired by recent electrochemical approaches, we investigate the
    couplings between ionic and electronic transport under AC driving. We show that
    conduction electrons of the channel walls participate in ionic current via capacitive
    electrochemical coupling, defining a critical frequency and length scale where
    electron-dominated conductivity emerges. We further analyze how electron–ion coupling
    modifies electro-osmotic flows and demonstrate that fluctuation-induced momentum
    transfer between the electrolyte and wall electrons produces distinct AC transport
    signatures, depending on the charge carrier polarity. Altogether, we establish
    a frequency-dependent transport matrix that couples ionic, electronic, and hydrodynamic
    flows. These findings establish AC nanofluidic transport as a powerful probe of
    interfacial phenomena under confinement and suggest new directions for engineering
    nanofluidic functionalities through electron–electrolyte coupling.
