21. Nanopore-based Single Molecule Determination of Polymer-cation Binding and Membrane Protein Dynamics
Topic: Nanobiotechnology
Published: 8/24/2010
Authors: Joseph Earl Reiner, John J Kasianowicz, Joseph William Robertson
Abstract: Polyethylene glycol (PEG) is a ubiquitous charge-neutral polymer having several useful properties. It has been used to estimate the diameter of functioning nanopores. In this talk I will describe how the detailed analysis of PEG induced current block ...

22. Nanoscale Measurements With the TSOM Optical Method
Series: OTHER
Topic: Nanobiotechnology
Published: 1/4/2010
Author: Ravikiran Attota
Abstract: A novel through-focus scanning optical microscope (TSOM - pronounced as 'tee-som') technique that produces nanometer dimensional measurement sensitivity using a conventional optical microscope by analyzing images obtained at different focus positions ...

24. Nanoscopic Porous Sensors
Topic: Nanobiotechnology
Published: 7/1/2008
Authors: John J Kasianowicz, Joseph William Robertson, Elaine Chan, Joseph Earl Reiner, Vincent M Stanford
Abstract: There are thousands of different nanometer-scale pores in biology,many of which act as sensors for specific chemical agents. Recent work suggests that protein and solid-state nanopores have many potential uses in a wide variety of analytical applicat ...

25. 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 ...

27. Probing Dynamic Fluorescence Properties of Single and Clustered Quantum Dots Towards Quantitative Biomedical Imaging of Cells
Topic: Nanobiotechnology
Published: 10/28/2009
Authors: Hyeong Gon Kang, Fuyuki Tokumasu, Matthew Lawrence Clarke, Zhenping Zhou, Jianyong Tang, Tinh Nguyen, Jeeseong Hwang
Abstract: We present results on dynamical fluorescence properties of bioconjugated nanocrystals or quantum dots (QDs) in different chemical and physical environments. A variety of QD samples were prepared and compared: isolated individual QDs, QDs aggregated ...
