Wide-Field Opto-Iontronic iSCAT Mapping of Interfacial Charging and Electrical Connectivity
Zhu Zhang, Sanli Faez
Spatial variations in electrical connectivity and interfacial ion accumulation can strongly influence electrochemical performance, yet these properties are difficult to visualize d…
Optical Voltammetry of redox processes inside a nanohole with opto-iontronic microscopy
Zhu Zhang, Haolan Tao, Cheng Lian +2
Cyclic Voltammetry (CV) is the most commonly used method in electrochemistry to characterize electrochemical reactions, usually involving macroscopic electrodes. Here we demonstrat…
Laser-patterned Thin-film Electrodes: Imaging Ion Accumulation and Trapped Nanoparticles
Itir Bakis Dogru Yuksel, Zhu Zhang, Marnix Vreugdenhil +3
This study introduces a straightforward electrode design featuring sharp edges with a curvature of a few hundred nanometers in radius, with which both ion accumulation and nanopart…
Origami Nano-gap Electrodes for Reversible Nanoparticle Trapping
Itir Bakis Dogru-Yuksel, Allard P. Mosk, Sanli Faez
We present a facile desktop fabrication method for origami-based nano-gap indium tin oxide (ITO) electrokinetic particle traps, providing a simplified approach compared to traditio…
Iontronic microscopy of a tungsten microelectrode: "seeing" ionic currents under an optical microscope
Zhu Zhang, Sanli Faez
Optical methods for monitoring the electrochemical reaction at the interface are advantageous because of their table-top setup and ease of integration into reactors. Here we apply…
Dark-field light scattering microscope with focus stabilization
Anna Peters, Zhu Zhang, Sanli Faez
We present detailed design and operation instructions for a single-objective inverted microscope. Our design is suitable for two dark-field modes of operation: 1- total internal re…
