How it works

The SEM Bulk Liquid Electrochemistry Sample Holder integrates a sealed microfluidic liquid cell with true bulk reference and counter electrodes positioned off-chip, enabling accurate electrochemical control within the SEM. Real reference electrodes (e.g., Ag/AgCl) provide stable potentials, while bulk counter electrodes (e.g., Pt) support consistent current flow, eliminating the instability and drift common in on-chip systems.

‍

During operation, electrolyte flows through the liquid cell while electrochemical cycling is performed on the working electrode under direct electron beam observation. This architecture decouples electrochemical performance from geometric and material limitations of on-chip microfabricated electrodes, delivering reproducible current voltage responses with well-defined redox peaks closely matching bulk electroanalytical behavior while simultaneously enabling nanometer resolution imaging in liquid environments.
