Selective Binding of RNAse B Glycoforms by Polydopamine-immobilized Concanavalin A

June 10, 2009
Author(s)
Todd A. Morris, Alexander W. Peterson, Michael J. Tarlov
Glycoanalysis is important in the manufacture and quality control of protein therapeutics. An emerging method for glycoanalysis is the use of lectin arrays. Critical to the performance of these arrays is the immobilization of the lectin molecules

A Method for Fabricating Conductometric Gas Sensors of Metal Oxide Nanotubes Formed in Porous Aluminum Oxide Membranes

February 2, 2009
Author(s)
Reit Artzi-Gerlitz, Kurt D. Benkstein, David L. Lahr, Joshua L. Hertz, Christopher B. Montgomery, John E. Bonevich, Stephen Semancik, Michael J. Tarlov
We describe a general, simple strategy for fabricating conductometric gas sensors from metal oxide nanotubes formed in nanoporous aluminum oxide membranes. In this approach, the aluminum oxide membrane serves as both a template for growth of the sensing

Quantifying the Surface Coverage of Conjugate Moleucles on Functionalized Nanoparticles

November 22, 2007
Author(s)
Leonard F. Pease III, De-Hao D. Tsai, Rebecca A. Zangmeister, M Zachariah, Michael J. Tarlov
Electrospray-differential mobility analysis (ES-DMA) represents an attractive tool to determine directly the coverage and conformation of long, flexible molecules on engineered nanoparticles. For example, nanoparticles coated with single-stranded DNA

Synthesis and Structural Characterization of Glucopyranosylamide Films on Gold

January 16, 2007
Author(s)
Mridula Kadalbajoo, J J. Park, A Opdahl, Hiromi Suda, Kitchens A. C, Jayne C. Garno, J Batteas, Michael J. Tarlov, Phillip DeShong
Stereoselective synthesis of a- and b-linked glucopyranosylamide derivatives via the in situ generation of glucosyl isoxazolines has been performed utilizing a modified Staudinger methodology. Glucopyranosylamides were derivatized with thiol

Electrochemical Study of Chitosan Films Deposited on Gold Electrodes

July 28, 2006
Author(s)
Rebecca A. Zangmeister, J J. Park, G W. Rubloff, Michael J. Tarlov
We report the electrochemical characterization of chitosan films deposited on gold electrodes. Cyclic voltammetry was used to characterize the deposition and electroactivity of chitosan coated gold electrodes. Chitosan films were found to deposit at a gold

Alkanethiols on Platinum: Multicomponent Self-Assembled Monolayers

March 14, 2006
Author(s)
D Y. Petrovykh, H Y. Kimura-Suda, A Opdahl, Lee J. Richter, Michael J. Tarlov, L J. Whitman
We have studied the formation of self-assembled monolayers (SAMs) of n-alkanethiols on platinum thin films using X-ray photoelectron spectroscopy (XPS), reflection-absorption infrared spectroscopy (RAIRS), spectroscopic ellipsometry (SE), and contact angle

Nucleobase Orientation and Ordering in Films of Single-Stranded DNA on Gold

January 11, 2006
Author(s)
D Y. Petrovykh, V Perez-Dieste, A Opdahl, H Y. Kimura-Suda, J M. Sullivan, Michael J. Tarlov, F J. Himpsel, L J. Whitman
The structure of single-stranded DNA (ssDNA) immobilized on surfaces is critical to applications exploiting the molecular recognition function of nucleic acids.1-3 Although traditional surface analysis can be applied to adsorbed biomolecules,1 the
