Surface-Plasmon-Resonance-Enhanced Cavity Ring-Down Detection

January 1, 2004
Author(s)
A C. Pipino, John T. Woodward IV, Curtis W. Meuse, Vitalii I. Silin
The cavity ring-down technique is used to probe the absolute optical response of the localized surface plasmon resonance (SPR) of a gold nanoparticle distribution to adsorption of trichloroethylene (TCE) and perchloroethylene (PCE) from the gas phase

Osteoblast Cell Membrane Hybrid Bilayers for Studying Cell-Cell Interactions

September 30, 2003
Author(s)
John T. Elliott, Alessandro Tona, John T. Woodward IV, Curtis W. Meuse, H M. Elgendy, Anne L. Plant
Osteopath-like cells were grown on a surface that presents cell membrane components to the cells in culture. The culture surface was a bilayer formed by the interaction of osteoblast plasma membrane vesicles with an alkanethiol monolayer. We examined the

Biomimetic Membranes on Metal Supports

May 1, 2003
Author(s)
John T. Elliott, Curtis W. Meuse, Vitalii I. Silin, Susan T. Krueger, John T. Woodward IV, T Petralli-Mallow, Anne L. Plant
Biological membranes are complex and dynamic structures. The biological functions associated with membranes involve a number of different molecular species, and theories of how the molecular species are organized are still evolving. The fluid mosaic model

Choosing a Cantilever for In Situ Atomic Force Microscopy

April 1, 2003
Author(s)
John T. Woodward IV
This manuscript is a non-peer reviewed, invited tutorial for Microscopy Today. It describes the issues involved in choosing a cantilever for atomic force microscope (AFM) imaging under fluids. In situ AFM imaging is an increasingly popular technique for

Isostructural Self-Assembled Monolayers, Part 1. Octadecyl 1-thiaoligo(ethylene oxides)

April 1, 2003
Author(s)
David J. Vanderah, Richard S. Gates, Vitalii I. Silin, D N. Zeiger, John T. Woodward IV, Curtis W. Meuse, Gintaras Valincius, B Nickel
The self-assembled monolayers (SAMs) of a series of octadecyl 1-thiaoligo(ethylene oxide)x disulfides {[S(CH 2CH 2O) xC 18H 37] 2}, where x = 4 to 8, were assembled on gold and characterized by reflection-adsorption infrared spectroscopy (RAIRS)

Thin Films of Collagen Affect Smooth Muscle Cell Morphology

March 4, 2003
Author(s)
John T. Elliott, Alessandro Tona, John T. Woodward IV, P L. Jones, Anne L. Plant
The purpose of this study was to provide a reproducible method for applying collagen to surfaces on which cells can be grown, and to characterize the resulting thin films of collagen protein with respect to molecular structure and cellular response
