We demonstrate an opto-electrokinetic technique for non-invasive particle manipulation on the surface of a parallel-plate indium tin oxide (ITO) electrode that is biased with an alternating current (AC) signal and illuminated with near-infrared (1064 nm) optical landscapes. This technique can generate strong microfluidic vortices at higher AC frequencies (>100 kHz) and dynamically and rapidly a...

Three dimensional single particle trapping and manipulation is an outstanding challenge in various fields ranging from basic physics to life sciences. By monitoring the response of a trapped particle to a designed environment one can extract its characteristics. In addition, quantum dynamics of a spatially scanned well-known particle can provide environmental information. Precise tracking and p...

We demonstrate selective trapping or rotation of optically isotropic dielectric microparticles by plasmonic near field in a single gold plasmonic Archimedes spiral. Depending on the handedness of circularly polarized excitation, plasmonic near fields can be selectively engineered into either a focusing spot for particle trapping or a plasmonic vortex for particle rotation. Our design provides a...

Manipulation of particles by ultrasonic waves is a primary technique in the fields precision manufacturing, materials engineering, and vitro diagnosis, since it can control motion objects sound field contactless noninvasive manner. In general, free field, such as focused plane wave generated single transducer only manipulate particle. While complex array should be actuated electric system, whic...

background: a highly efficient genetic transformation system is essential for a successful genetic manipulation of the african violet (saintpaulia ionantha wendl.).objectives: developing a particle bombardment-based genetic transformation system for the african violet.materials and methods: a local cultivar of the african violet from guilan province was used for transformation experiments. the ...

Manipulation of particles at the surface of a droplet can lead to the formation of structures with heterogeneous surfaces, including patchy colloidal capsules or patchy particles. Here, we study the assembly and rearrangement of microparticles confined at the surface of oil droplets. These processes are driven by electric-field-induced hydrodynamic flows and by 'electro-shaking' the colloidal p...

The contact-SLAM problem is a broad class of grasping and manipulation problem and it is very important to robotic manipulation tasks, particularly when contacts are likely to be intermittent. Several researchers have developed particle filters for C-SLAM problems that estimate the state of manipulated objects, some geometric properties, and their contacts, but the effects of various designing ...

This paper explores the planning and control of a manipulation task accomplished in conditions of high uncertainty. Statistical techniques, like particle filters, provide a framework for expressing the uncertainty and partial observability of the real world and taking actions to reduce them. We explore a classic manipulation problem of planar batting, but with a new twist of shape, pose and imp...

We describe commonly used strategies for the control of charged particle beams and the manipulation of their properties. Emphasis is placed on relativistic beams in linear accelerators and storage rings. After a brief review of linear optics, we discuss basic and advanced beam control techniques, such as transverse and longitudinal lattice diagnostics, matching, orbit correction and steering, b...
