A Magnetically and Electrically Powered Hybrid Micromotor in Conductive Solutions: Synergistic Propulsion Effects and Label-Free Cargo Transport and Sensing
Yue Wu, Sivan Yakov, Afu Fu +1
Electrically powered micro- and nanomotors are promising tools for in-vitro single-cell analysis. In particular, single cells can be trapped, transported and electroporated by a Ja…
Electro-Orientation and Electro-Rotation of Metallodielectric Janus Particles
Daniel Sofer, Gilad Yossifon, Touvia Miloh
The electro-rotation (EROT) and electro-orientation (EOR) behavior of metallodielectric (MD) spherical Janus particles (JP) are studied analytically and verified experimentally. Th…
Designing with Iontronic Logic Gates -- From a Single Polyelectrolyte Diode to Small Scale Integration
Barak Sabbagh, Noa Edri Fraiman, Alex Fish +1
This article presents the implementation of on-chip iontronic circuits via small-scale integration of multiple ionic logic gates made of bi-polar polyelectrolyte diodes. These ioni…
Microvalve-Based Tunability of Electrically Driven Ion Transport Through a Microfluidic System with Ion-Exchange Membrane
Barak Sabbagh, Sinwook Park, Gilad Yossifon
Microfluidic channels with embedded ion permselective medium under the application of electric current are commonly used for electrokinetic processes as on-chip ion concentration p…
Active control of ion transport within a nanofluidic system

The ability to induce regions of high and low ionic concentration adjacent to a permeselective membrane or nanochannel subject to an externally applied electric field (a phenomenon…
Mobile Microelectrodes: Towards active spatio-temporal control of the electric field and selective cargo assembly
Alicia M Boymelgreen, Tov Balli, Touvia Miloh +1
With an eye towards next-generation, smart, micro/nanofluidic devices, capable of responding to external stimuli or changes in environment, we demonstrate a means to achieve dynami…
Time-dependent ion transport in heterogeneous permselective systems
Yoav Green, Gilad Yossifon
The current study extends previous analytical and numerical solutions of chronopotentiometric response of one-dimensional systems consisting of three layers to the more realistic t…
Effect of Induced-Charge Electro-Kinetics on Concentration-Polarization in a Microchannel-Nafion System
Sinwook Park, Gilad Yossifon
Induced-charge electro-osmosis (ICEO) is shown to control the length scale of the diffusion layer (DL), which in turn, affects the diffusion limited ion transport through the micro…
Competition between Induced-Charge Electro-Osmosis and Electro-Thermal Effects around a Weakly-Polarizable Microchannel Corner
Matan Zehavi, Alicia Boymelgreen, Gilad Yossifon
The microchannel corner is a common inherent component of most planar microfluidic systems and thus its influence on the channel flow is of significant interest. Application of an…
Bridging the Gap between an Isolated Nanochannel/pore System and Communicating Multipore Heterogeneous Membrane System
Yoav Green, Sinwook Park, Gilad Yossifon
To bridge the gap between single/isolated pore systems to multi-pore systems, such as membranes/electrodes, we studied an array of nanochannels with varying interchannel spacing th…
Probing space charge and resolving overlimiting current mechanisms at the micro-nanochannel interface
Jarrod Schiffbauer, Uri Liel, Neta Leibowitz +2
We present results demonstrating the space charge-mediated transition between classical, diffusion-limited current and surface-conduction dominant over-limiting current in a shallo…
Effect of geometry on concentration polarization in realistic heterogeneous permselective systems
