A single-beam optical trapping of microscopic particles and biological cells is demonstrated by using higher-order mode Nd:YAG laser beams at mu m for the first known time. using phase modulation and interferometry to manipulate a single particle in an optical trap1.
An optical trap, or optical tweezers, provides a method for performing nano scale operations. While optical tweezers cannot directly resolve the details of a nano structure. Optical techniques provide high sensitivity at the nanoscale and can be used to measure single biomolecule mechanics.
90 To do so, a bead is attached to one end of a molecule with the other end anchored to a nonmoving surface. It is possible to examine the stretch response in a molecule under an applied load by moving the optical trap away from the anchored molecule and observing the bead's.

We have developed a technique of generating a micro-bubble inside an optical trap by using a material (Mo-based Soft Oxometalate (SOM) compound) that absorbs at the trapping laser wavelength. Using the inherent momentum of light, particles are trapped in the high intensity field of a focused laser beam thus allowing for the manipulation of microscopic particles.

The chapter then covers the trapping and manipulation of particles in intermediate micro-to-nano scale size (optical tweezer). The problematic case of trapping ultrasmall nanoparticles (nano tweezer) is covered last. Finally, the chapter presents the most recent area of using thermal effects to trap particles in a liquid environment.
Optical tweezers are a unique tool for manipulating neutral particles in micro/nano scale and have wide applications in biological and physical fields.
However, the majority of tasks with optical tweezers are carried out manually at present time. The manual operation is incompetent in dynamic environment. Automated manipulation of micro/nano particles with optical tweezers can improve both the. of the optical trap, and this feature offers distinct advantages when a single optical trap ‘juggles’ multiple particles (33– 35).
Tracking in 3-D using quadrant photodiodes has been described (27,28). In principle, two-photon ﬂuorescence in-Trafﬁc ; 2: – duced by the high-intensity optical tweezers can also provide. However, confinement and fine-scale manipulation of micro and nanoscale particles remains a significant challenge in the field.
At present, particle trapping methods based on acoustic, electrokinetic, magnetic, and optical fields are utilized, but some of these methods are limited to particles with specific material properties and/or bulky.

Optical tweezers work on the principle that a highly focused continuous-wave laser beam 1, typically with a Gaussian (TEM 00 mode) intensity profile, can optically trap and manipulate micro- and nano-sized dielectric particles.
In such techniques, created by using a high-quality microscope objective, the particles are trapped within the narrow. use of optical forces to trap dielectric microspheres held within a thin layer of water and vesicles in onion cells. The typical mechanical forces involved are on the scale of piconewtons (10 12 N).
Relative to this scale, hydrody-namical forces (drag and di usion) on the microspheres and vesicles are substantial. Thus, the optical trap pro. Optical trapping and laser interferometry enable the non-invasive manipulation of colloids, which can be used to investigate the microscopic mechanics of surrounding media or bound macromolecules.
For efficient trapping and precise tracking, the sample media must ideally be homogeneous and quiescent whereas such conditions are usually not.
Optical tweezers provides dynamic, flexible manipulation of specific single cells. Optical tweezers uses the gradient force of light to trap particles using a highly-focused laser beam (Ashkin et al., ), and has been used in many research applications, such as measuring.
But, unlike optical tweezers, they are fixed at a spot and can only capture particles close to them. In their earlier work, researchers had managed to transport nano-scale cargo using plasmonic tweezers integrated with magnetic nano-robots.
However, the tweezers could not be used for certain types of colloids such as magnetic nanoparticles. An electronically controlled acoustic tweezer was used to demonstrate two acoustic manipulation phenomena: superposition of Bessel functions to allow independent manipulation of multiple particles and the use of higher-order Bessel functions to trap particles in larger regions than is possible with first-order traps.
The principles of optical manipulation A single beam, gradient-force optical trap is based on the interaction of a micron-sized dielectric particle with a beam of light that is brought to a diffraction-limited focal spot.

Optical tweezers utilize optical traps to hold micron-sized polystyrene or silica beads as force sensors to manipulate single macromolecules attached to the beads [4,54,55].An expanded and collimated infrared laser beam (with typical nm wavelength) is focused by a high-numerical-aperture objective lens.
The optical pickup was used to trap both polystyrene colloids and red blood cells, where the trap strength was determined by measuring the viscous drag required to break the particle out of the trap. In this, the trap was translated within a microfluidic channel and the limiting velocity at which the trapped colloid was dragged out of the trap.
