21. Resolving three-dimensional shape of sub-50 nm wide lines with nanometer-scale sensitivity using conventional optical microscopes
Topic: Nanobiotechnology
Published: 7/29/2014
Authors: Ravikiran Attota, Ronald G Dixson
Abstract: We experimentally demonstrate that the three-dimensional (3-D) shape variations of nanometer-scale objects can be resolved and measured with sub-nanometer scale sensitivity using conventional optical microscopes by analyzing 3-D optical data using th ...

22. SEM Induced Shrinking of Solid State Nanopores for Single Molecule Detection
Topic: Nanobiotechnology
Published: 9/22/2011
Authors: Anmiv Prahbu, Kevin J Freedman, Joseph William Robertson, Zhorro Nikolov, John J Kasianowicz, MinJun Kim
Abstract: We have investigated the shrinkage of solid state nanopores by a scanning electron microscope and find the process to be reproducible and dependant beam parameters such as the accelerating voltage and electron flux. The shrinking phenomenon does ...

23. Steering Acoustically Propelled Nanowire Motors towards Cells in a Biologically Compatible Environment using Magnetic Fields
Topic: Nanobiotechnology
Published: 12/10/2013
Authors: Suzanne Ahmed, Wei Wang, Lamar O. Mair, Robert D. Fraleigh, Sixing Li, Luz Angelica Castro, Mauricio Hoyos, Tony Jun Huang, Thomas E. Mallouk
Abstract: The recent discovery of fuel-free propulsion of nanomotors using acoustic energy has provided a new avenue for using nanomotors in biocompatible media. Crucial to the application of nanomotors in biosensing and biomedical applications is the ability ...

24. Surface-Engineered Nanomaterials as X-ray Absorbing Adjuvant Agents for Auger-Mediated Chemo-Radiation
Topic: Nanobiotechnology
Published: 4/30/2013
Authors: Robert Francis Cook, Sang-Min Lee, De-Hao D. Tsai, Vincent A Hackley, Martin W. Brechbiel
Abstract: We demonstrate a prototype approach to formulate gold nanoparticle (AuNP)‹based X‹ray absorbing adjuvant agents through surface‹engineering of cisplatin pharmacophore (PtII) with lipoic acid‹modified polyacrylate (denoted as PtII‹AuNPs). Design of Pt ...

25. Synapsable quadruplex-mediated fibers
Topic: Nanobiotechnology
Published: 5/3/2013
Authors: Veronika A Szalai, Miguel Angel Mendez
Abstract: We have fabricated and characterized a novel DNA based nanofiber created by synergistic self-assembly of guanine quadruplex (Hoogsteen base pairing) and double-stranded DNA (Watson-Crick base pairing). The assembly of our nanofibers occurs in several ...

26. TSOM Method for Nanoelectronics Dimensional Metrology
Topic: Nanobiotechnology
Published: 11/18/2011
Author: Ravikiran Attota
Abstract: Through-focus scanning optical microscopy (TSOM) is a relatively new method that transforms conventional optical microscopes into truly three-dimensional metrology tools for nanoscale to microscale dimensional analysis. TSOM achieves this by acquirin ...

27. TSOM Method for Semiconductor Metrology
Topic: Nanobiotechnology
Published: 4/18/2011
Authors: Ravikiran Attota, Ronald G Dixson, John A Kramar, James Edward Potzick, Andras Vladar, Benjamin D. Bunday, Erik Novak, Andrew C. Rudack
Abstract: Through-focus scanning optical microscopy (TSOM) is a new metrology method that achieves 3D nanoscale measurement resolution using conventional optical microscopes; measurement sensitivities are comparable to what is typical using Scatterometry, SEM ...

28. Temperature sculpting in yoctoliter volumes
Topic: Nanobiotechnology
Published: 2/14/2013
Authors: Joseph E Reiner, Joseph William Robertson, Daniel L Burden, Lisa K Burden, Arvind Kumar Balijepalli, John J Kasianowicz
Abstract: The ability to perturb large ensembles of molecules from equilibrium led to major advances in understanding reaction mechanisms in chemistry and biology. Here, we demonstrate the ability to control, measure, and make use of rapid temperature changes ...

29. The Stability and Surface Coverage of Polymer Stabilized Gold Nanoparticles
Topic: Nanobiotechnology
Published: 10/2/2010
Authors: Karl B Sebby, Elisabeth Mansfield
Abstract: NA

30. Through-focus Scanning Optical Microscopy
Topic: Nanobiotechnology
Published: 12/31/2011
Author: Ravikiran Attota
Abstract: Through-focus scanning optical microscopy (TSOM) method provides three-dimensional information (i.e. the size, shape and location) about micro- and nanometer-scale structures. TSOM, based on a conventional optical microscope, achieves this by acquiri ...
