In recent years, several new methods have been developed to precisely manipulate small
particles using optical, electric, acoustic, magnetic, or fluidic fields. Automated fluidic …

Hydrodynamic trapping allows for the confinement and manipulation of small objects in free
solution, away from solid boundaries and without the need for optical or magnetic fields. In …

Colloidal particles can create reconfigurable nanomaterials, with applications such as color-
changing, self-repairing, and self-regulating materials and reconfigurable drug delivery …

A rapid electrokinetic patterning (REP) microfluidic chip is fabricated consisting of two ITO
conductive glass plates separated by polyethylene terephthalate (PET) spacers with a …

The rapid electrokinetic patterning (REP) technique has been demonstrated to enable
dynamic particle manipulation in biomedical applications. Previous studies on REP have …

Control of electroosmotic flows in a two-layer microfluidic device with crossed channels is
used to counteract Brownian diffusion in aqueous solution for three-dimensional trapping of …

We developed a 'hybrid actuator system'to precisely control the position of a micro-particle at
high speed in a microfluidic chip. The hybrid actuator system benefits from two actuator …

Colloidal particles provide the ideal building blocks for the next generation of microdevices,
such as advanced sensors and precision drug delivery systems. However, many such …

The ability to precisely manipulate micro-and nano-scale objects has been a major driver in
the progression of nanotechnologies. In this proceedings we describe a form of micro …

We describe a quantitative study of vortex generation due to non-equilibrium electrokinetics
near a micro/nanochannel interface. The microfluidic device is comprised of a microchannel …
