11. Nanometrology Using Through-Focus Scanning Optical Microscopy Method
Topic: Nanobiotechnology
Published: 12/21/2011
Authors: Ravikiran Attota, Richard M Silver
Abstract: We present an initial review of a novel through-focus scanning optical microscopy (TSOM) imaging method that produces nanometer dimensional measurement sensitivity using a conventional bright-field optical microscope. In the TSOM method a target is ...

12. 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 ...

13. 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 ...

14. O2 A-band line parameters to support atmospheric remote sensing. Part II: The rare isotopologues
Topic: Nanobiotechnology
Published: 7/21/2011
Authors: Joseph Terence Hodges, David A Long, Daniel K Havey, S. S. Yu, M Okumura, Charles E Miller
Abstract: Frequency-stabilized cavity ring-down spectroscopy (FS-CRDS) was employed to measure over 100 transitions in the R-branch of the b1Σg+←X3Σg-(0,0) band for the rare O2 isotopologues. The use of 17O- and 18O-enriched mixtures allowed fo ...

16. Methodology for imaging of nano-to-microscale water condensation dynamics on complex nanostructures
Topic: Nanobiotechnology
Published: 6/11/2011
Authors: Konrad Rykaczewski, John Henry Scott
Abstract: By transferring of a small part of a macroscale sample to a novel thermally insulated sample platform we are able to mitigate flooding and electron heating problems typically associated with Environmental Scanning Electron Microscopy imaging of water ...

17. Carbon Nanotubes Activate Store Operated Calcium Entry (SOCE) in Blood Platelets Manifested by STIM-1 Clustering
Topic: Nanobiotechnology
Published: 6/3/2011
Authors: Silvia Helena De Paoli Lacerda, Jana Semberova, Karel Holada, Olga Simakova, Steven D Hudson, Jan Simak
Abstract: Intravascular effects of carbon nanotubes (CNTs) as a result of their various biomedical applications or environmental/occupational exposure raise serious safety concerns. CNTs potentiate arterial thrombosis in animal models;[1, 2] however, a mechani ...

Topic: Nanobiotechnology
Published: 10/29/2010
Authors: Kavita M Jeerage, Stephanie M. LaNasa, Holly A. Hughes, Damian Sky Lauria, Stephanie J. Bryant, Andrew J Slifka
Abstract: Scanning electrochemical microscopy has been used to examine the molecular transport properties of photopolymerized poly(ethylene glycol) (PEG) hydrogels having different mesh sizes. Both the molecular weight (508 Da or 3000 Da) of the PEG diacrylate ...
