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 their geometry and coated regions. Specifically, we studied a lollipop-shaped complex particle where its head is coated with gold while its tail is left bare. Due to their distinct electrical properties (i.e. electrical polarizability) the particle exhibits force equilibrium where opposite dielectrophoretic forces…

Alternating current electrokinetic properties of gold-coated microspheres.

Experimental observations of dielectrophoresis and electrorotation measurements of gold-coated polystyrene microspheres as a function of frequency and for several electrolyte conductivities are in agreement with predictions for the force and torque on the induced dipole of a perfectly polarizable metal sphere.

Propulsion of Active Colloids by Self-Induced Field Gradients.

It is demonstrated theoretically and experimentally that the critical frequency at which the particle reverses direction can be characterized by a nondimensional parameter which is a function of electrolyte concentration and particle size.

Electrorotation of a metallic coated Janus particle under AC electric fields

Electrorotations (EROTs) of the Pt-silica Janus particles are measured in different conditions under rotating electric fields. Unlike simple particles, we find that the rotation direction of a Janus

The models and methods presented in this review are sufficiently general to be of use in a broad range of applications for biological dielectrophoresis and particle electrokinetics and may be extended further to the case of nonspherical particles, where alignment torques can be considered.

Reconfiguring active particles by electrostatic imbalance.

A general strategy to reconfigure active particles into various collective states by introducing imbalanced interactions is presented, and this strategy of asymmetry-driven active self-organization should generalize rationally to other active 2D and three-dimensional materials.

Cellular dielectrophoresis: Applications to the characterization, manipulation, separation and patterning of cells

There is need for a critical report to integrate the many new features ofDEP for cellular applications, and a review of the basic theory and current applications of DEP, specifically for cells is presented.

Electro-orientation of a metal nanowire counterbalanced by thermal torques.

The rotational diffusion of electrically polarized metal nanowires suspended in an electrolyte is studied and good agreement with theoretical predictions is found.

Distinct and independent dielectrophoretic behavior of the head and tail of sperm and its potential for the safe sorting and isolation of rare spermatozoa

This research is a proof of concept that DEP has the potential to automate and improve the processing of semen samples, especially those containing only rare spermatozoa.
