Applied Research Associates Presents Technological Advances at "Biodetection Technologies 2012" June 28-29
Conference Features Dr. Rosalie Multari from Applied Research Associates, Expert in Detection & Identification of Biological ThreatsJune 2012
The upcoming“Biodetection Technologies 2012” conference on June 28-29 in Washington, D.C., features Applied Research Associates (ARA) Laser-Induced Breakdown Spectroscopy (LIBS) bio-diagnostic expert Dr. Rosalie Multari presenting scientific advances in “Laser-Induced Breakdown Spectroscopy as a Rapid, In-situ Bio Diagnostic.”
Speaking to an audience of senior corporate executives, government biodefense leaders and academic bioscientists from across the United States, Dr. Multari will present the latest scientific advances in LIBS developed by ARA.
“ARA has demonstrated that LIBS could be used as a bio-diagnostic to rapidly differentiate samples contaminated with bio targets such as Hanta Virus, Anthrax, Tularemia, Salmonella and E. coli. The capability for differentiating strains in addition to species in laboratory-prepared samples has also been shown,” said Dr. Multari. “Using a new method of analyzing LIBS spectra developed here at ARA, we have the potential to deliver biodetection tools for food safety, medical, military, industrial and academic testing applications that can yield analysis results within seconds to minutes with very little training.”
Biodetection Advances for Food Safety, Industrial Processing, Environmental Monitoring and Research
LIBS is a form of atomic emission spectroscopy. In LIBS, a laser pulse is used to create a spark on a sample from which light emissions are collected and input into a spectrometer. The resulting spectra can be subsequently analyzed to determine the composition of the sample or the sample identity.
In her work at ARA, Dr. Multari has contributed to recent advances in mathematical modeling techniques being applied to LIBS spectra, opening up new avenues of use.
These new applications have been created by analyzing “spectral fingerprints” as opposed to individual spectral lines to identify chemical and biological targets of interest. ARA now has the potential to make portable LIBS instruments programmed to detect multiple bio targets on surfaces and in liquids that can be used by nonscientific field technicians and yield results in seconds to minutes.
ARA is currently working to deploy this technology in various commercial applications related to food safety and is investigating its potential as a medical diagnostic applied to real clinical samples.
