12. Quantifying Dithiothreitol Displacement of Functional Ligands from Gold Nanoparticles
Topic: Nanobiotechnology
Published: 10/27/2012
Authors: De-Hao D. Tsai, Frank W DelRio, Sherrie R. Elzey, Suvajyoti S. Guha, Michael Russel Zachariah, Vincent A Hackley, Melanie P Shelton
Abstract: Dithiothreitol (DTT)-based displacement is widely utilized for separating ligands from their gold nanoparticle (AuNP) conjugates, a critical step for differentiating and quantifying surface-bound functional ligands and therefore the effective surface ...

13. Disentangling the effects of polymer coatings on silver nanoparticle agglomeration, dissolution, and toxicity to determine mechanisms of nanotoxicity
Topic: Nanobiotechnology
Published: 9/1/2012
Authors: Justin M Zook, Melissa Danielle Halter, Danielle Cleveland, Stephen E Long
Abstract: Silver nanoparticles (AgNPs) are frequently coated by a variety of polymers, which may affect various intertwined mechanisms of toxicity, including agglomeration and dissolution rate. Here, we measure how citrate, dextran, poly(ethylene glycol) (PEG ...

14. A Lectin-Based Gold Nanoparticle Assay for Probing Glycosylation of Glycoproteins
Topic: Nanobiotechnology
Published: 4/17/2012
Authors: Germarie Sanchez-Pomales, Todd A. Morris, James Falabella, Michael J Tarlov, Rebecca A Zangmeister
Abstract: We report a glycoanalysis method in which lectins are used to probe the glycans of glycoproteins that are adsorbed on gold nanoparticles. A model mannose-presenting glycoprotein, ribonuclease B (RNase B), and the therapeutic monoclonal antibody (mAb) ...

15. Tumor Necrosis Factor Interaction with Gold Nanoparticles
Topic: Nanobiotechnology
Published: 3/14/2012
Authors: De-Hao D. Tsai, Sherrie R. Elzey, Frank W DelRio, Robert I. MacCuspie, Suvajyoti S. Guha, Michael Russel Zachariah, Athena M Keene, Jeffrey D Clogston, Vincent A Hackley
Abstract: We report on a systematic investigation of molecular conjugation of tumor necrosis factor protein-α (TNF) onto gold nanoparticles (AuNPs) and the subsequent binding behavior to its antibody (anti-TNF). We employ a combination of physical and spe ...

16. 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 ...

17. 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 ...

18. 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 ...

19. 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 ...

20. 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 ...
