Microparticle manipulation using inertial forces

Microparticle manipulation using inertial forces

We demonstrate controlled manipulation of large quantities of microparticles on a surface using inertial forces. Motion is induced by applying a periodic parabolic wave form to a shear-polarized piezoelectric plate coupled to a substrate on which the particles reside. Particles move in steps of 10 to 50 nm per cycle, and the particle motion is mass selective. Particle velocity is varied by chan...

Robot Vibration Control Using Inertial Damping Forces

Wireless on-chip microparticle manipulation using pulse-driven dielectrophoresis

A chip with which to manipulate microparticles using wireless power transfer and pulse-driven dielectrophoresis has been designed and fabricated using a 0.18-μm CMOS process. The chip enables microparticle manipulation under a 0.7-V power supply and a 13-MHz clock, which are generated on the chip by means of an on-chip coil, a rectifier, and a Schmitt trigger circuit.

Two-Dimensional Vision-Based Autonomous Microparticle Manipulation using a Nanoprobe

Autonomous micromanipulation has been an emerging interest in constructing and assembling microobjects. Manual assembly and manipulation of small-scale objects through teleoperation is possible, however autonomy is necessary for large-volume manipulation and manufacturing. In this study, we discuss a two-dimensional autonomous manipulation system, which is based on an optical microscope and a n...

Manipulation Microparticle Polystyrene Microparticles as Handles

Varun Saxena Using a fixed beam with a fundamental Gaussian mode, a gradient force optical trap was used to translate a single cell using a carboxylated polystyrene bead as a handle. Currently, the force with which the optical trap can manipulate an individual cell alone is very weak. In fact, the inadequate nature of the optical trap on living cells has prevented this technique from being usef...
