Feedback Control of Optically Trapped Particles

December 17, 2011
Jason J. Gorman, Arvind K. Balijepalli, Thomas W. LeBrun
Optical trapping is a method for manipulating micro- and nanoscale particles that is widely used in biophysics and colloid science, among other areas. This method uses optical forces to confine the position of a particle to a localized region, which is

A Flexible System Framework for a Nanoassembly Cell Using Optical Tweezers

January 1, 2006
Arvind K. Balijepalli, Thomas W. LeBrun, Satyandra K. Gupta
The optical tweezers instrument is a unique tool for directed assembly of nanocomponents. In order to function as a viable nanomanufacturing tool, a software architecture is needed to run the optical tweezers hardware, provide an effective user interface

Three-dimensional Scanning Optical Tweezers

December 5, 2005
Thomas W. LeBrun, T W. Hwang, I Y. Park, Jun-Feng Song, Yong-Gu Lee, Nicholas G. Dagalakis, Cedric V. Gagnon, Arvind K. Balijepalli
There are several new tools for manipulating microscopic objects. Among them, optical tweezers (OT) has two distinguishing advantages. Firstly, OT can easily release an object without the need of a complicated detaching scheme. Secondly, it is anticipated

A Modular System Architecture for Agile Assembly of Nanocomponents using Optical Tweezers

September 10, 2005
Arvind K. Balijepalli, Thomas W. LeBrun, Cedric V. Gagnon, Yong-Gu Lee, Nicholas G. Dagalakis
In order to realize the flexibility optical trapping offers as a nanoassembly tool, we need to develop natural and intuitiveinterfaces to assemble large quantities of nanocomponents quickly and cheaply. We propose a system to create such aninterface that

Development of Multiple Beam Optical Tweezers

June 1, 2005
Dongjin Lee, Thomas W. LeBrun, Arvind Balijepalli, Jason J. Gorman, Cedric V. Gagnon, Daehie Hong, Esther H. Chang
This paper presents the design of a multiple beam optical tweezers instrument used for manipulating micro/nano-sized components. The basic equations used in designing the optical tweezers are derived and the stable and time-sharing multiple beam optical
