Title of dissertation: MODELING AND EXPERIMENTAL TECHNIQUES TO DEMONSTRATE NANOMANIPULATION WITH OPTICAL TWEEZERS Arvind K. Balijepalli, Doctor of Philosophy, 2011 Dissertation directed by: Professor S. K. Gupta Department of Mechanical Engineering Dr. Thomas W. LeBrun National Institute of Standards and Technology The development of truly three-dimensional nanodevices is currently impeded by t...

Previous studies on nanomanipulation using Atomic Force Microscope (AFM) go through the scandesign-manipulation-scan cycle, in which an operator does not have any real-time visual feedback during manipulation. In this paper, a simple model of tip-substrate-object interactive forces has been presented for the qualitative and quantitative analysis. Based on this model, the real-time tip-substrate...

: In many cases in experimental science, the instrument interface becomes a limiting factor in the efficacy of carrying out unusual experiments or prevents the complete understanding of the acquired data. We have developed an advanced interface for scanning probe microscopy (SPM) that allows intuitive rendering of data sets and natural instrument control, all in real time. The interface, called...

We report nanomanipulation and nanoassembly of carbon nanotubes (CNTs) through nanorobotic manipulation inside electron microscopes. A hybrid nanorobotic manipulation system, which is integrated with a nanorobotic manipulator inside a transmission electron microscope (TEM) and nanorobotic manipulators inside a scanning electron microscope (SEM), is used. The elasticity of a multiwalled CNT (MWN...

Nanometric objects attract huge interest due to their new and unexpected physical and chemical properties [1], which may allow the development of new technological devices. The study of these nano-objects is seriously limited by the fact that well-established conventional tools can not be easily applied in this size range. The development of new instruments and methodologies is necessary to all...
