Spatial Pattern Formation, Size Selection, and Directional Flow of Polymer Latex Particles by Laser Trapping Technique

TL;DR: In this paper, a method and apparatus for control of optical trap arrays and formation of particle arrays is presented, where a laser and a time variable diffractive optical element are used to allow dynamic control of trap arrays.

TL;DR: Optophoresis as mentioned in this paper consists of subjecting particles to various optical forces, especially optical gradient forces, and more particularly moving optical gradients, so as to obtain useful results, which represents a practical approach to probing the inner workings of a living cell, preferably without any dyes, labels or other markers.

TL;DR: In this article, the authors survey experimental results obtained by the employment of the technique called "scanning laser micromanipultion" and demonstrate that this method can be applied for micro-machining, optical switching and electrochemistry, as demonstrated by a series of examples.

TL;DR: In this paper, a dispersing medium containing plural types of particles is let to flow in a flow path formed by a flow cell, and the flow cell is irradiated with interfering light to form interference fringes of a pattern of stripes.

TL;DR: In this paper, it is hypothesized that similar acceleration and trapping are possible with atoms and molecules using laser light tuned to specific optical transitions, and the implications for isotope separation and other applications of physical interest are discussed.

TL;DR: Use of lasers has revolutionized the study and applications of radiation pressure, and it is now possible to optically accelerate, slow, stably trap, and manipulate micrometer-sized dielectric particles and atoms.

TL;DR: Simultaneous laser manipulation, spectroscopy, and ablation of a dye-doped poly(methyl methacrylate) latex particle in water was demonstrated in this paper, where a minute hole with its diameter and length of ≈sub μm and 4-7 μm, respectively, was fabricated on an optically trapped latex particle (4 − 7 μm diameter) by laser ablation.

TL;DR: Properly fashioned electromagnetic fields coupled to microscopic dielectric objects can be used to create arrays of extended crystalline and noncrystalline structures that depend on the presence of both light and polarizable matter.
