Development of the NIST Prototype Advanced Biometrology Laboratory

Ongoing
Currently, NIST is investing in a new type of metrology laboratory that is focused on the unique reference material and high quality assay protocols that are needed in the regenerative medicine and biotechnology communities. The laboratory design is centered on automation that can set up 1000’s of

Development of Proteomics-Based Methods for Protein Quantification

Ongoing
Reference measurement procedures and standard reference materials help ensure that routine clinical assays provide accurate results across different laboratories and over time. Lists of such higher-order methods are published by the Joint Committee for Traceability in Laboratory Medicine (JCTLM)

Development of Reference Methods and Reference Materials for Proteins

Ongoing
Accuracy and comparability of clinical assays is essential for timely and accurate medical interventions. However, studies have shown that large variations in results can occur among routine clinical assays. A clinical comparison among 14 commercial assay platforms revealed more than 20-fold

Development of Serum-Based SRMs to Assess Nutritional Status

Ongoing
Vitamin deficiencies are generally considered rare in the U.S., but a growing body of evidence suggests that certain deficiencies may be more prevalent than originally thought. For example, it has been estimated that 10 % to 15 % of adults over the age of sixty are affected by vitamin B 12

Development of SRM 2669 for Accurate Assessment of Arsenic Exposure

Ongoing
Arsenic exposure in the U.S. population is an important part of the NHANES program conducted by CDC because dietary exposure to arsenic can cause serious health effects. A major challenge in the arsenic exposure assessment is that arsenic exists as various species in nature, and the toxicity of

Development of SRM 955c Toxic Elements in Caprine Blood

Completed
Intended Impact Over the last three decades, NIST, with support from the Centers for Disease Control (CDC), and in conjunction with the New York State Department of Health’s (NYSDOH) Wadsworth Center, has produced a number of frozen whole blood certified reference materials containing endogenous

Device-level Anomaly fRamEwork (DARE)

Ongoing
A collaborative NIST team is taking a multi-disciplinary approach in cybersecurity, wireless communications, and machine learning. The DARE project leverages NIST's diligent approach and capabilities, including detailed use cases, design of experiments with rigorous multilayer measurements, and

DFT Benchmarking

Ongoing
Since its inception exactly 50 years ago this year, density-functional theory (DFT) has evolved from an exotic idea of physicists into the most-widely used tool for the computational prediction of materials’ structures and electronic, optical, magnetic, and mechanical properties. While DFT presents

DFT Repositories and Informatics

Ongoing
Historically, the printed article has served as the medium de rigueur for the dissemination of scientific information. This works well when the context and results of an experiment or theory fit on a few pages; however, it is insufficient as a publication medium for many computational studies. For

DHS-OEC Next Generation Networks – Priority Services Evaluation Project

Ongoing
The Department of Homeland Security’s Office of Emergency Communication (DHS-OEC) is responsible for administering both the Government Emergency Telecommunications Service (GETS) and Wireless Priority Service (WPS) programs. Both programs offer their users an alternative method for call completion

Diamond NV Center Magnetometry

Completed
A flaw in a crystal might not be an intuitive choice for a measurement tool, but the nitrogen-vacancy (NV-) defect in diamond is something special. Using light, we prepare the NV- center’s the quantum spin state, it interacts with magnetic fields, and we read out the resulting spin state through

Dietary Supplement Laboratory Quality Assurance Program (DSQAP)

Ongoing
Approximately 75% of the U.S. population takes dietary supplements, including vitamins and mineral supplements, representing an annual expenditure of more than $20 billion. Regulations, driven by reported cases of inaccurate labeling, adulteration, contamination (with pesticides, heavy metals, or

Dietary Supplement Laboratory Quality Assurance Program (DSQAP) Consortium

Ongoing
The objective of the DSQAP Consortium is to develop and evaluate measurement methods and standards to support quality and safety for the dietary supplement testing community. Approximately 75% of the U.S. population takes dietary supplements, including vitamins and mineral supplements, representing
