Novel Detection Method for DNA Hybridization Based on Molecular Spotlighting

February 1, 2000

Author(s)

T H. Huang, Michael J. Tarlov

A new platform for monitoring hybridization of thiol-derivatized DNA probes (SH-DNA) immobilized on gold surfaces is currently being developed. The gold surface is modified with mixed monolayers of the SH-DNA probes and 6-mercaptohexanol. In fluorescence

Surface Plasmon Resonance Measurements of DNA Probe/Target Hybridization Reactions on Gold Surfaces

February 1, 2000

Author(s)

G B. Saupe, Michael J. Tarlov

Optimizing and understanding the parameters involved in thin film DNA hybridizations are important to emerging DNA sensor array technologies. We recently constructed a Surface Plasmon Resonance (SPR) instrument and software for measuring the small

Molecular-Scale Characterization of the Reaction of Ozone with Decanethiol Monolayers on Au(111)

October 20, 1999

Author(s)

G Poirier, T M. Herne, Carl C. Miller, Michael J. Tarlov

The chemical reaction of ozone with decanethiol monolayers on Au(111) was characterized using X-ray photoelectron spectroscopy and scanning tunneling microscopy. Our results show that exposure to ozone results in oxidation of the thiol terminus. The

Electrostatic Interactions of Redox Cations with Surface-Immobolized and Solution DNA

May 1, 1999

Author(s)

A B. Steel, T M. Herne, Michael J. Tarlov

Electrochemical Quantitation of DNA Immobilized on Gold

November 15, 1998

Author(s)

A B. Steel, T M. Herne, Michael J. Tarlov

We have developed an electrochemical method to quantify the surface density of DNA immobilized on gold. The surface density of DNA, more specifically the number of nucleotide phosphate residues, is calculated from the amount of cationic redox marker

Using Self-Assembly to Control the Structure of DNA Monolayers on Gold: A Neutron Reflectivity Study

September 30, 1998

Author(s)

R Levicky, T M. Herne, Michael J. Tarlov, Sushil K. Satija

Neutron reflectivity was used to determine the concentration profiles of oligomeric DNA monolayers on gold in the high salt (1M NaCl). These monolayers are of interest as model DNA probe systems used in diagnostic devices. To facilitate its attachment, the

Characterization of DNA Probes Immobilized on Gold Surfaces

September 24, 1997

Author(s)

T M. Herne, Michael J. Tarlov

Observation of Hybridization and Dehybridization of Thiol-Tethered DNA Using Two-Color Surface Plasmon Resonance Spectroscopy

April 9, 1997

Author(s)

K A. Peterlinz, R M. Georgiadis, T M. Herne, Michael J. Tarlov

Patterning of Self-assembled Alkanethiol Monolayers on Silver by Microfocus Ion and Electron Beam Bombardment

April 1, 1994

Author(s)

John G. Gillen, Scott A. Wight, Joe Bennett, Michael J. Tarlov

Decanethiol [CH3(CH2)9SH] self-assembled monolayer films on silver substrates have been irradiated in selected areas by focused ion or electron bombardment. Subsequent immersion of the irradiated sample in a solution of a fluoromercaptan [CF3(CF2)2(CH2)2SH

Molecular Imaging Secondary Ion Mass Spectrometry for the Characterization of Patterned Self-assembled Monolayers on Silver and Gold

January 1, 1994

Author(s)

John G. Gillen, J. Bennett, Michael J. Tarlov, Donald R. Burgess Jr.

Self-assembly of alkanethiol monolayers on gold and silver substrates is a fast, easy, and convenient method for preparing stable organic films with well-defined physical and chemical properties that can be modified by changing the terminal functional

UV Photopatterning of Alkanethiolate Monolayers Self-Assembled on Gold and Silver

June 1, 1993
