Observation of a Single-Beam Gradient Force Acoustical Trap for Elastic Particles: Acoustical Tweezers.
We demonstrate the trapping of elastic particles by the large gradient force of a single acoustical beam in three dimensions. Acoustical tweezers can push, pull and accurately control both the position and the forces exerted on a unique particle. Forces in excess of 1 micronewton were exerted on polystyrene beads in the submillimeter range. A beam intensity less than 50 W/cm^{2} was required, ...
متن کاملTheoretical Aspects of Single-beam Multitrapping Acoustical Tweezers
1 Abstract The concept of a multitrapping acoustical tweezer based on a focused ultrasound beam is presented and theoretically investigated. The beam is described in the paraxial approximation and it is generated by a concave transducer. The resulting focused beam exerts a radiation force on a small particle that is much smaller than the incident wavelength (i.e. the so-called Rayleigh scatteri...
متن کاملObservation of a single-beam gradient-force optical trap for dielectric particles in air.
A single-beam gradient-force optical trap for dielectric particles, which relies solely on the radiation pressure force of a TEM(00)-mode laser light, is demonstrated in air for what is believed to be the first time. It was observed that micrometer-sized glass spheres with a refractive index of n=1.45 remained trapped in the focus region for more than 30 min, and we could transfer them three di...

متن کاملAcoustical force nanolithography of thin polymer films
Nanomachining of thin polymer resist films with an atomic force microscope (AFM) is a promising route for the fabrication of nanoscale devices. In order to enhance the controllability of the nanomachining process an in-plane acoustic wave is coupled to the sample support. This enhances the intermittent force exerted by the AFM tip. The lateral resolution reached by this method is only limited b...
