Nanoplasmonics and Three-Dimensional Plasmonic Metamaterials

Ongoing
Plasmonic materials are composed of metals and insulators that are ordered in geometric arrangements with dimensions that are fractions of the wavelength of light. Research groups are experimenting with a variety of geometric approaches, but all aim to exploit surface plasmons, which are light

NIST/EDRN Cancer Biomarker Collaboration

Completed
Our lab is one of the EDRN Biomarker Reference Laboratories working with the EDRN discovery labs to improve the quality of the measurements done on new cancer biomarkers for early detection of cancer and for cancer risk. TECHNICAL APPROACH Evaluate current assays used for detection of cancer

NIST Flow Cytometry Standards Consortium 

Ongoing
Advances in cell and gene-based therapeutics as well as other regenerative medicine products have increased the need for high quality, robust, and validated measurements for cell characterization. Flow cytometry, including imaging cytometry, has emerged as an important platform due to its ability to

NIST HER2 Genomic DNA Standard Reference Material, SRM® 2373

Ongoing
The amplification of the gene for HER2 occurs in approximately 20 to 25% of breast cancers. The accurate measurement of this biomarker is important for the proper treatment with anti-HER2 therapeutics. Clinical laboratories are beginning to utilize accurate and sensitive diagnostic tests based on

NIST PS1 Primary Standard for quantitative NMR (Benzoic Acid)

Completed
With explicit SI linkage, the overall impact of this apical reference material is profound—this primary standard, as well as forthcoming members of its class, provides technology transfer of chemical purity realization to the commercial sector for characterization of many thousands of organic

NIST Urine Albumin Standardization Program

Ongoing
Kidney disease is a major global economic and public health issue, with chronic kidney disease (CKD) representing one of the top 10 most prominent causes of death worldwide. The public health and economic impact of CKD and other kidney diseases has led to the need for the accurate detection of

Pacific Marine Mammal Health Assessments (PMMHA)

Ongoing
Pacific Marine Mammal Health Assessments (PMMHA), which began in Fall 2010, are an expansion of NIST marine mammal health assessment collaborations that began in 2002 with bottlenose dolphin wild populations. NIST has a history of involvement in marine mammal health assessment related work

Pathogen Detection and Identification: The Next Generation of Analyses

Ongoing
Human disease resulting from pathogens represents a tremendous burden on the health care system. Many hospitals have adopted new, rapid polymerase chain reaction (PCR)-based detection systems because the time to diagnose and begin effective treatment has a direct impact on patient survival and

Quantification of Cells with Specific Phenotypic Characteristics

Ongoing
Internationally recognized and validated reference standards are currently not available in the field of cellular phenotyping by flow cytometry. The World Health Organization (WHO) has issued an open letter to the manufacturers of CD4 + T-cell enumeration technologies for the HIV/AIDS epidemic

Serology and Neutralization Assays for COVID-19

Ongoing
Multiplexed bead-based SARS-CoV-2 serological assay We have developed a validated multiplexed bead-based SARS-CoV-2 serological assay that measures different antibodies produced by a patient (IgG, IgM, IgA). In collaboration with the NIST Applied and Computational Mathematics Division, we have

Standards Development to Ensure Reliable Breath Analysis in the Field

Ongoing
Numerous volatile organic compounds (VOCs) have been identified in human breath. These compounds can be produced by the body or by organisms in the body (e.g., bacteria or viruses) and provide a non-invasive window into human health. Inexpensive point-of-care devices are being developed to diagnose

Standards for Metagenomics

Ongoing
Metagenomics is a powerful technology combining high-throughput (a.k.a. “next-generation”) sequencing with advanced bioinformatics to identify and quantify mixtures of organisms in a sample. Metagenomics workflows consist of 4 main steps: Sample collection: location, amount, storage, etc. Extraction

Vitamin D Metabolites Quality Assurance Program (VitDQAP)

Completed
Interlaboratory comparison studies of the VitDQAP supported the reliability of vitamin D measurements, including determination of 25-hydroxyvitamin D2, 25-hydroxyvitamin D3, and 3- epi-25-hydroxyvitamin D3 in human serum and plasma. Results from the comparison studies helped participants to make
