1. Accurate Stochastic Simulations Using Graphics Hardware: Nanoassembly With the Optical Tweezers
Published: 3/1/2010
Authors: Arvind Kumar Balijepalli, Thomas W LeBrun, Satyandra K. Gupta
Abstract: Significant speedup is possible when using the Graphics Processing Unit (GPU) for stochastic particle simulations. A simulation of freely diffusing spherical particles using Langevin's equation has been developed and the results from the CPU an ...

2. A Flexible System Framework for a Nanoassembly Cell Using Optical Tweezers
Published: 1/1/2006
Authors: Arvind Kumar Balijepalli, Thomas W LeBrun, Satyandra K. Gupta
Abstract: 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 inter ...

3. Three-dimensional Scanning Optical Tweezers
Published: 12/5/2005
Authors: Thomas W LeBrun, T W. Hwang, I Y Park, Jun-Feng Song, Yong-Gu Lee, Nicholas G Dagalakis, Cedric Gagnon, Arvind Kumar Balijepalli
Abstract: 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 antici ...

4. A Modular System Architecture for Agile Assembly of Nanocomponents using Optical Tweezers
Published: 9/10/2005
Authors: Arvind Kumar Balijepalli, Thomas W LeBrun, Cedric Gagnon, Yong-Gu Lee, Nicholas G Dagalakis
Abstract: 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 ...

6. Characterization of Optical Traps Using On-Line Estimation Methods
Published: 8/26/2005
Authors: Jason John Gorman, Thomas W LeBrun, et al
Abstract: System identification methods are presented for the estimation of the characteristic frequency of an optically trapped particle. These methods are more amenable to automated on-line measurements and are believed to be less prone to erroneous results ...

7. Development of Multiple Beam Optical Tweezers
Published: 6/1/2005
Authors: Dongjin Lee, Thomas W LeBrun, Arvind Kumar Balijepalli, Jason John Gorman, Cedric Gagnon, Daehie Hong, Esther H Chang
Abstract: 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 opti ...

8. Virtual Environment for Manipulating Microscopic Particles with Optical Tweezer
Published: 7/1/2003
Authors: Thomas W LeBrun, Kevin W Lyons, Yong-Gu Lee
Abstract: In this paper, we use virtual reality techniques to define an intuitive interface to a nanoscale manipulation device. This device utilizes optical methods to focus laser light to trap and reposition nano-to-microscopic particles. The underlying physi ...

10. Micro-Mirror Array Control of Optical Tweezer Trapping Beams
Published: 8/28/2002
Authors: Nicholas G Dagalakis, Thomas W LeBrun, J Lippiatt
Abstract: The efficiency of optical tweezer manufacturing depends on the number of trapping beams available. Micro optics technology offers the opportunity to significantly increase the number of trapping beams without a significant increase of the cost or siz ...
