Advanced Spectral Analysis: Two-Dimensional Correlation Spectroscopy (2DCOS)

Ongoing
When a series of spectra are acquired from a sample as a function of temperature, pressure, electric field strength, concentration, or any experimental parameters, conventional spectral analysis is performed by monitoring the intensity change at a specific frequency. However, such a single frequency

Biofabrication of Tissue Engineered Constructs

Ongoing
OCT imaging was assessed using a model scaffold-cell system consisting of a polysaccharide-based hydrogel seeded with human Jurkat cells. Four test systems were used: hydrogel seeded with live cells, hydrogel seeded with heat-shocked or fixed dead cells and hydrogel without any cells. Time series

Biofilm Models to Evaluate Structure-Function Relationships

Ongoing
Biofilms are complex 3D microbial structures that exist throughout nature including on our skin and gut mucosa, in waterways, and in soil. They are typically composed of multiple microbial species surrounded by proteins, polysaccharides, and extracellular DNA woven together into a hydrated matrix

Biomaterials for Oral Health

Completed
NIST along with its partners has a long commitment to scientific excellence with demonstrated impact in improving the oral health of the public. NIST researchers are leaders in this field and create a community by engaging other researchers, industry, and regulatory agencies to address urgent needs

Building Measurement Confidence for Cell Characterization

Ongoing
NIST collaborates with key stakeholders in industry, other government agencies, and academia to develop measurement assurance strategies and advanced measurement capabilities for cell characterization. Data and concepts developed through workshops and laboratory programs inform the development of

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

DNA Origami for Precise Manufacturing of Nanoscale Structures

Completed
The base pairing of adenine to thymine and guanine to cytosine to form DNA provides a robust molecular recognition scheme that can be used to create a wide variety of well-ordered nanostructures. DNA origami, which uses a long scaffold strand folded together by specific sets of short staple strands

High-Sensitivity IR Spectroscopy of Proteins

Ongoing
Infrared (IR) absorption spectroscopy has been widely used as a non-invasive, label-free characterization method for the chemical identification and structure of complex biomolecules. Fourier-transform IR (FT-IR) technology is commonly used to characterize proteins and other biological molecules

Label-free imaging of cells and their extracellular matrix by SPR imaging

Ongoing
Cellular remodeling of their neighboring environment, extracellular matrix (ECM), is an important biological process from development biology, to wound healing, to diseases and cancers – this is a challenging process to measure and quantify. Surface plasmon resonance imaging (SPRI) has been

Metrology of Magnetic Materials

Ongoing
Currently, the bulk of this project is focused on three main pieces: Thermal MagIC: An SI-Traceable Method for 3D Thermal Magnetic Imaging and Control Magnetic Refrigeration Magnetic Standard Reference Materials (SRMs) Thermal MagIC (MAGnetic Imaging and Control) is focused on developing new

Nanocalorimetry Measurements

Ongoing
Accurate thermodynamic measurements are essential to understand fundamental properties of materials, providing direct and quantifiable insight into the thermodynamics of thin film reactions and phase transitions. Going forward, new classes of materials may only be synthesized as thin films, a scale

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

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

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

Synthetic Fecal Metabolite Calibrant Solution (RGTM 10212)

Ongoing
Metabolomics is an exciting and dynamic field in life sciences that harnesses cutting-edge technologies to identify and characterize small molecules, or metabolites, within cells, tissues, or organisms, collectively known as the metabolome. The wealth of evidence in the literature underscores the
