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 – A Global Concern Kidney disease is a significant global public health and economic issue, with Chronic Kidney Disease (CKD) ranking among the top 10 worldwide causes of death. The critical need for early and accurate diagnosis, effective treatment management, and ongoing patient...

Pacific Marine Mammal Health Assessments (PMMHA)

Completed
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...

Reference Material 8038 H5N1 (Avian Influenza) Synthetic RNA Fragments

Completed
In response to the H5N1 avian influenza outbreak, NIST has developed a Reference Material (RM) for PCR-based assays. This material contains 3 vials with RNA fragments for HA (Part A), NA (Part B), and MP (Part C). The Reference Material Information Sheet (RMIS) for this material contains information...

Reference Materials and Methods for Vitamin D Binding Protein

Ongoing
Vitamin D is essential for bone health, and vitamin D deficiency can lead to rickets in children and osteomalacia (soft bones) in adults. Vitamin D status is typically monitored through measurement of the metabolite 25-hydroxyvitamin D [25(OH)D] in serum. Most 25(OH)D is tightly bound to its...

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...
