Dielectrophoretic response and electro-deformation of soft bioparticles interacting with a metallo-dielectric Janus active particle
Donggang Cao, Gilad Yossifon
Active (self-propelling) particles have emerged as innovative microscale tools in the field of single cell analysis with the advantages of being untethered, remotely controlled, hy…
Programmable Motion of Optically Gated Electrically Powered Engineered Microswimmer Robots
Matan Zehavi, Ido Rachbuch, Sinwook Park +3
Here, we report on a new class active particles capable of dynamically programmable motion powered by electricity. We have implemented physical principles that separate the propuls…
The influence of frequency and gravity on the orientation of active metallo-dielecric Janus particles translating under a uniform applied alternating-current electric field
Alicia Boymelgreen, Golak Kunti, Pablo Garcia Sanchez +1
Theoretical and numerical models of active Janus particles commonly assume that the metallo-dielectric interface is parallel to the driving applied electric field. However, our exp…
Dielectrophoretic Equilibrium of Complex Particles
Tom Elkeles, Pablo Garcia-Sanchez, Wu Yue +2
In contrast to the commonly used spherical Janus particles, here we used engineered Janus particles that are fabricated using photolithography technique for precise control over th…
Active Particles as Mobile Microelectrodes for Selective Bacteria Electroporation and Transport
Yue Wu, Afu Fu, Gilad Yossifon
Self-propelling micromotors are emerging as a promising microscale and nanoscale tool for single-cell analysis. We have recently shown that the field gradients necessary to manipul…
Analysis of Cargo Loading Modes and Capacity of an Electrically-Powered Active Carrier
Xiaoye Huo, Yue Wu, Alicia Boymelgreen +1
The use of active colloids for cargo transport offers unique potential for applications ranging from targeted drug delivery to lab-on-a-chip systems. Previously, Janus particles (J…
Electrothermal active control of preconcentrated biomolecule plugs
Sinwook Park, Gilad Yossifon
Concentration polarization (CP) based biomolecule preconcentration is highly effective in enhancing the detection sensitivity, yet fails to precisely and dynamically control the lo…
Extended space charge near non-ideally selective membranes and nanochannels
Jarrod Schiffbauer, Neta Leibowitz, Gilad Yossifon
We demonstrate the role of selectivity variation in the structure of the non-equilibrium extended space-charge using 1D analytic and 2D numerical Poisson-Nernst-Planck models for t…
