Nanomanipulation modeling and simulation
A novel approach to better model nanomanipulation of a nanosphere lying on a stage via a pushing scheme is presented. Besides its amenability to nonlinear analysis and simulation, the proposed model is also effective in reproducing experimental behavior commonly observed during AFM-type …

Design and fabrication of nanotweezers for nanomanipulation
… nanotweezers to serve as the hands and arms for nanomanipulation. Most such devices are not fabricated using completely batch processes and lack the consistency, feature definition, and ease of production required for general use. In this project, we propose a completely batch fabricated …

Modeling and Experimental Techniques to Demonstrate Nanomanipulation With Optical Tweezers
The development of truly three-dimensional nanodevices is currently impeded by the absence of effective prototyping tools at the nanoscale. Optical trapping is well established for flexible three-dimensional manipulation of components at the microscale. However, it has so far not been demonstrated …

Ferroelectric Barium Titanate Nanowires: Synthesis, Properties, and Device Applications
With the assistance of nanomanipulation and electron beam deposition techniques, a nanoscale energy converter device was fabricated using an individual BaTiO3 nanowire. In this device, due to the piezoelectric effect, voltage response was generated from the BaTiO3 nanowire by a periodically varying …

Design, Fabrication, Testing of CNT Based ISFET and Characterization of Nano/Bio Materials Using AFM
… on silicon surfaces. Since AFM based nanomanipulation and nanomachining is highly controllable, nanochannels are precisely scratched in the area between the source and drain of the FET where the inversion layer is after the ISFET is activated. Thus, a bundle of CNTs are able to be …
