Development of a Chemically Relevant Artificial Fingerprint Material

September 16, 2015

Author(s)

Edward Sisco, Jessica L. Staymates, Katherine Schilling, John Gillen

The development of a chemically relevant artificial fingerprint material as well as a preliminary method for fingerprint deposition is discussed herein. More specifically the improvement of an artificial sweat material, an artificial sebaceous material

Strategies for Potential Age Dating of Fingerprints through the Diffusion of Sebum Molecules on a Non-porous Surface

July 17, 2015

Author(s)

Shinichiro Muramoto, Edward Sisco

Age dating of fingerprints can have a significant impact in forensic science, as it has the potential to facilitate the judicial process by assessing the relevance of a fingerprint found in a crime scene. However, no reliable method currently exists that

Quantifying the Degradation of TNT and RDX in a Saline Environment with and without UV-Exposure

April 14, 2015

Author(s)

Edward Sisco, Marcela N. Najarro, Candice Bridge, Roman Aranda

Terrorist attacks in a maritime setting, such as the bombing of the USS Cole in 2000, or the detection of underwater mines requires the development of proper protocols to collect and analyze explosive material from a marine environment. In addition to

Trace detection and competitive ionization of erythritol tetranitrate in mixtures using direct analysis in real time mass spectrometry

April 9, 2015

Author(s)

Thomas P. Forbes, Edward R. Sisco

Direct analysis in real time (DART) mass spectrometry was used for trace detection of the nitrate ester explosive, erythritol tetranitrate (ETN), and its sugar alcohol precursor, erythritol. The present investigation revealed the impact of competitive

Rapid Detection of Sugar Alcohol Precursors and Corresponding Nitrate Ester Explosives using Direct Analysis in Real Time Mass Spectrometry

March 30, 2015

Author(s)

Edward Sisco, Thomas Forbes

This work highlights the rapid detection of nitrate ester explosives and their sugar alcohol precursors by direct analysis in real time mass spectrometry (DART-MS) using an off-axis geometry. Demonstration of the effect of various parameters, such as ion

Mass Spectrometry Detection and Imaging of Organic and Inorganic Explosive Device Signatures using Desorption Electro-Flow Focusing Ionization

June 26, 2014

Author(s)

Thomas Forbes, Edward Sisco

We demonstrate the coupling of desorption electro-flow focusing ionization (DEFFI) with in-source collision induced dissociation (CID) for the mass spectrometric (MS) detection and imaging of explosive device components, including both organic, e.g

Chemical Imaging of Artificial Fingerprints by Desorption Electro-Flow Focusing Ionization Mass Spectrometry

May 19, 2014

Author(s)

Thomas Forbes, Edward Sisco

Desorption electro-flow focusing ionization (DEFFI) mass spectrometry was used to image chemical distributions of endogenous, e.g., fatty acids, and trace exogenous compounds, e.g., explosives, narcotics and lotions, in deposited and lifted artificial

Evaluation of C60 Secondary Ion Mass Spectrometry for the Chemical Analysis and Imaging of Fingerprints

January 22, 2013

Author(s)

Edward R. Sisco, Leonard Demovanville, John G. Gillen

The feasibility of using C60 Cluster Primary Ion Bombardment Secondary Ion Mass Spectrometry (C60 SIMS) for the analysis of the chemical composition of fingerprints is evaluated. It was found that C60 SIMS could be used to detect and image the spatial
