Author(s)
Elissa H. Williams, Albert Davydov, John A. Schreifels, Mulpuri V. Rao, Abhishek Motayed, Siddarth Sundaresan, Peter Bocchini, Lee J. Richter, Gheorghe Stan, Kristen L. Steffens, Rebecca A. Zangmeister
(0001) 4H-SiC was functionalized with 3-aminopropyltriethoxysilane (APTES) and subsequently biotinylated for the immobilization of streptavidin. Atomic force microscopy (AFM), x-ray photoelectron spectroscopy (XPS), ellipsometry, fluorescence microscopy

A Lectin-Based Gold Nanoparticle Assay for Probing Glycosylation of Glycoproteins

April 17, 2012
Author(s)
Germarie Sanchez-Pomales, Todd A. Morris, James Falabella, Michael J. Tarlov, Rebecca A. Zangmeister
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)

Carbohydrate-Functionalized Surfactant Vesicles for Controlling Glycan Density

March 15, 2012
Author(s)
Monique A. Makos, Rebecca A. Zangmeister
We report on the development of a method for rapidly characterizing the glycan binding properties of lectins. Catanionic surfactant vesicles were prepared that spontaneously formed in water and remained stable at room temperature for months. By varying the

Method for Determining the Absolute Number Concentration of Nanoparticles from Electrospray

October 27, 2011
Author(s)
Mingdong M. Li, Suvajyoti S. Guha, Rebecca A. Zangmeister, Michael J. Tarlov, Michael R. Zachariah
We have developed a simple, fast, and accurate method to measure the absolute number concentration of nanoparticles in solution. The method combines electrospray-differential mobility analysis (ES-DMA) with a statistical analysis of droplet induced

Recent Advances in Electrochemical Glyco-biosensing

April 8, 2011
Author(s)
Rebecca A. Zangmeister, Germarie Sanchez-Pomales
Biosensors based on electrochemical transduction mechanisms have recently made advances into the field of glycan analysis. These glyco-biosensor assays offer simple, rapid, sensitive and economical approaches to the measurement need for rapid glycan

Quantification and Compensation of Unintentional Analyte Aggregation in Electrospray Sampling

March 30, 2011
Author(s)
Mingdong M. Li, Suvajyoti S. Guha, Rebecca A. Zangmeister, Michael J. Tarlov, Michael R. Zachariah
Electrospray (ES) sources are commonly used to introduce non-volatile materials (e.g. nanoparticles, proteins, etc.) in to the gas phase for characterization by mass spectrometry and ion mobility. Recent studies in our group using electrospray ion mobility

Nanotube Length Distributions Measured from Suspension by Electrospray-Differential Mobility Analysis

December 4, 2009
Author(s)
Leonard F. Pease III, De-Hao D. Tsai, Jeffrey A. Fagan, Barry J. Bauer, Rebecca A. Zangmeister, Michael J. Tarlov, Michael R. Zachariah
We present the first systematic characterization of well dispersed, length sorted single-walled carbon nanotubes (SWCNTs) by electrospray-differential mobility analysis (ES-DMA). Although understanding geometric properties of SWCNTs including their length

Equilibrium Electrostatics of Responsive Polyelectrolyte Monolayers

January 14, 2009
Author(s)
Rebecca A. Zangmeister, Rastislav Levicky, Kang Wang
The physical behavior of polyelectrolytes at solid-liquid interfaces presents challenges both in measurement and in interpretation. An informative, yet often overlooked, property that characterizes the equilibrium organization of these systems is their

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

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

DNA Displacement Assay Integrated into Microfluidic Channels

July 1, 2004
Author(s)
Rebecca A. Zangmeister, Michael J. Tarlov
This paper describes the development of a unique fluorescence based DNA diagnostic assay incorporated into a microfluidic channel that does not require labeling of the target sequence prior to analysis. The assay is based on the displacement of a short

Selective DNA Sensing Elements Integrated Into Microfluidic Channels

December 1, 2003
Author(s)
Rebecca A. Zangmeister, Michael J. Tarlov
This paper describes the development of a unique fluorescence based DNA diagnostic assay that does not require pre-labeling of the target oligomer prior to analysis. The assay uses polyacrylamide hydrogel plugs immobilized in microfluidic channels, and is

DNA Hydrogel Plugs Immobilized in Microfluidic Channels with Improved Stability

February 28, 2002
Author(s)
Rebecca A. Zangmeister, K G. Olsen, David J. Ross, Michael J. Tarlov
It has been previously demonstrated that DNA, modified on the 5' end with an acrylic acid group, can be incorporated into a polyacrylamide hydrogel matrix. These types of DNA containing gels have recently been immobilized in plastic microfluidic channels
