3D Orientation Imaging

Ongoing
We have developed 3D orientation imaging methods for both infrared (IR) and coherent anti-Stokes Raman scattering (CARS) signals. The two approaches are complementary to each other. The IR-based 3D orientation imaging is broadly applicable to any pair of non-parallel IR transition dipole moments

Orthogonal Measurements

Ongoing
Definitions: Orthogonal measurements: Measurements that use different physical principles to measure the same property of the same sample with the goal of minimizing method-specific biases and interferences. Complementary measurements: Measurements that corroborate each other to support the same

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

Per- and Polyfluoroalkyl Substances (PFAS)

Ongoing
Perfluorinated and polyfluorinated alkyl substances (PFAS) constitute a family of compounds that are distinguished by partial or complete fluorination of alkyl hydrocarbons. Dubbed “forever chemicals”, the unique chemistry of PFAS imparts a high level of stability, making the compounds resistant to

Performance Metrics for Proteomics

Ongoing
Intended Impact Proteomics experiments designed to identify protein markers specific to a particular disease or disease state rely on repeatable identification of proteins within a control set. Repeatability provides statistical assurance that clear differences between two sets (e.g. sick vs

Photonic Dosimetry

Ongoing
With this effort, NIST is responding to industry needs for traceable, measurement solutions that can resolve spatial variations of absorbed dose at the level of individual components on a silicon wafer or bacteria on surgical instruments. Presently, there is only limited traceability to national

Photopolymerization for Biomaterials

Completed
This project responds to priorities of National Institute of Dental and Craniofacial Research (NIDCR/NIH) for oral health by establishing clinical guidance/standards for adequate photocuring of restorative dental composites. Also, this project is intended to advance the knowledge relevant to thermal

Point-of-Care Pharmaceutical Manufacturing & Precision Medicine

Ongoing
We are employing quality by design (QbD) and risk assessment (cause-and-effect) approaches to investigate production technologies ( e.g., drop on demand or inkjet printing platforms) and appropriate analytical control strategies for point-of-care manufacture of narrow therapeutic index drugs

Protein Preservation

Completed
This project is an integral part of a cooperative effort – led by NIST, and partially funded by NIH/ NIBIB – which includes the University of Wisconsin, the University of Colorado, and the University of Connecticut. We use the following approach to develop measurement solutions for biopharmaceutical

Quantitative Flow Cytometry Measurements

Ongoing
Flow cytometry is an essential tool for: basic biotechnological and immunological research, the clinical discovery of potential therapeutics, development and approval of drugs and devices, disease diagnosis, and therapeutic treatment and monitoring For example, flow cytometry is commonly used in pre

Reliable Vaccine Storage

Completed
Our group examines best practices for the storage and monitoring of vaccines in partnership with the Centers for Disease Control and Prevention’s (CDC) Vaccine Supply and Assurance Branch. Vaccines are highly temperature sensitive, and inappropriate storage conditions can render them ineffective

RMAT Laboratory Programs

Ongoing
Examples of Current Activities: Cell Counting and viability are key measurements critical for decision making from R&D to manufacturing. We recently developed an approach for evaluating the quality of cell counting measurements through experimental design and statistical analysis that does not

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

Single-Cell Manipulation and Measurement

Ongoing
Mammalian cells are an important source material for applications in regenerative medicine, gene therapy, engineering biology, and genome editing. Traditional tools for manipulating mammalian cells operate at a bulk cell population level without precision manipulation of individual cells

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

Standards to Support Biological Detection in the Field

Ongoing
NIST is working in partnership with the Department of Homeland Security Science and Technology Directorate (DHS S&T) to develop methods, guidance, standards, and reference materials to support and improve our Nation's ability to detect and respond to suspected biothreat incidents. Specific

Standards to Support Biothreat Detection

Ongoing
Since 9/11 and the subsequent anthrax attacks in 2001, suspicious white powder incidents continue to occur within the US, often requiring Federal law enforcement response. Suspect samples are sent to public health laboratories for confirmatory evaluation, which can take hours to weeks to receive

Storage Stability of Freeze-Dried Proteins

Completed
Intended Impact Work in this project will enable industry to develop rational formulation approaches for freeze-drying, thus facilitating the manufacture safer, longer lasting biopharmaceuticals, with less time and resource cost required for stabilization. Biopharmaceuticals are the fastest growing
