Founded in 2019, this program was motivated by the rapid decriminalization of adult use and medical use of cannabis by state governments. This has led to
The goal of this focus area is to leverage the wealth of chemical information present in fingerprint deposits for novel forensic applications. This includes
The goal of this focus area is to enhance the measurement science capabilities and address measurement science challenges present in the analysis of fire debris
NMR spectroscopy is routinely used to analyze chemical mixtures in the liquid phase. It is far less common for these techniques to be applied to vapor-phase
The Surface and Trace Chemical Analysis Group conducts research across various forensic science disciplines. The overall goal is to address measurement science
NIST is measuring the trace chemical signatures and quantities of trace residues and background levels that contaminate surfaces associated with the concealment
Ion mobility spectrometry (IMS) is widely used for national security and law enforcement, placed at key transportation checkpoints such as airports and border
Provide the underpinning measurement science needed to advance threat detection, improve the accuracy of forensics measurements and ensure the reliability of
With increasing backlogs and more complex samples, forensic chemistry laboratories need new technologies that rapidly provide accurate analytical results. Many
As part of a multi-year interagency agreement between the Office of Standards of the Department of Homeland Security and NIST, NIST is developing measurement
Metamaterials are tailor-made photonic composites--combinations of materials designed to achieve optical properties not seen in nature. The properties stem from
The "first-of-its-kind" in an entirely new class of reference material, NIST PS1 Primary Standard for quantitative NMR (Benzoic Acid) is now available! The PS
NIST is collaborating with the DEA and the Federal Criminal Police Office of Germany – Bundeskriminalamt (BKA) to develop a web-based forensic drug chemistry
NIST, the nation’s reference lab for chemical measurements, helps crime labs and medical first responders rapidly detect and identify opioids, particularly new
Obtaining high confidence field detection, identification, and quantification of microbial samples remains a challenge. Since 9/11 and the subsequent anthrax
Thermal desorption ambient mass spectrometry decouples analyte desorption and ionization. Here, analytes are thermally desorbed directly from a primary surface
Toxicology represents the newest focus area for our group. The goal of this work is to compliment traditional toxicological research with development of
Screening of people and their belongings including luggage, vehicles, and packages for the presence of trace residues of explosives and narcotics (trace
