Band 3 Modifications in Plasmodium Falciparum-Infected AA and CC Erythrocytes Assayed by Autocorrelation Analysis Using Quantum Dots

March 1, 2005
Author(s)
F Tokumasu, R M. Fairhurst, G R. Ostera, N J. Brittain, Jeeseong C. Hwang, T E. Wellems, J A. Dvorak
The molecular stability of hemoglobin is critical for normal erythrocyte functions, including oxygen transport. Hemoglobin C (HbC) is a mutant hemoglobin that has increased oxidative susceptibility due to an amino acid substitution ( 6: Glu to Lys). The

Effects of Surface Functionality and Humidity on The Adhesion Force and Chemical Contrast Measured With AFM

January 1, 2005
Author(s)
Tinh Nguyen, Xiaohong Gu, lijiang chen, Michael J. Fasolka, Kimberly Briggman, Jeeseong C. Hwang, Jonathan W. Martin
The ability to probe chemical heterogeneity with nanometer scale resolution is essential for developing a molecular level understanding of a variety of phenomena occurring at surfaces of materials. One area that could benefit greatly from nanoscale

Near-Field Polarimetric Characterization of Polymer Crystallites

August 1, 2004

Lori S. Goldner, S N. Goldie, Michael J. Fasolka, F Renaldo, Jeeseong Hwang, Jack F. Douglas
We use near-field polarimetry (NFP) to investigate thin film crystallites of isotactic polystyrene (iPS). NFP micrographs enabled quantitative optical characterization of the birefringence in these specimens with sub-diffraction limited resolution

Fourier Analysis Near-Field Polarimetry for Measurement of Local Optical Properties of Thin Films

July 1, 2003
Author(s)
Lori S. Goldner, Michael J. Fasolka, S Nougier, H P. Nguyen, Garnett W. Bryant, Jeeseong Hwang, K D. Weston, Kathryn L. Beers, A Urbas, Edwin L. Thomas
We present measurements of the local dichroism and birefringence of thin film specimens us ing techniques that combine near-field scanning optical microscopy (NSOM) and a novel polarization modulation (PM) polarimetry utilizing Fourier analysis of the

Near-Field Polarimetric Characterization of Semi-Crystalline Polymer Systems

March 1, 2003
Author(s)
S N. Goldie, Michael J. Fasolka, Lori S. Goldner, Jeeseong C. Hwang, Kathryn Beers
We have studied crystallization in thin films of isotactic polystyrene (iPS) to better understand the morphology and formation of these structures through the use of polarization modulation near-field scanning optical microscopy (PM-NSOM). Polymer
