Development of differential absorption LIDAR Technologies

Ongoing
The basic processes involved in elastic backscatter LIDAR are as follows. A laser emits a pulse of light (typically a few nanoseconds), and as the pulse propagates, the photons interact with molecules and aerosol particles. Some of these, the interactions with aerosols, such as Mie and Rayleigh
membrane

Measurement Techniques for Membranes and Membrane Proteins

Ongoing
Use of synthetic cell membrane mimics allow simplification and complete control of a complicated system, and incorporation of selected elements under physiological conditions. We are furthering a technology originally developed at NIST using model lipid membranes supported on surfaces for
nano-biophotonics collage

Nano-biophotonics for molecular imaging

Ongoing
Nano-biophotonics consists of four broad areas: molecular bioimaging; nano-biosensors; multiplexed bioassays ; and nanotechnology-based medical practices for diagnosis and therapy. Success in these areas is challenged by the underlying complexity of biological systems. Major levels of complexity and
NIST standard reference material (SRM) for the verificaiton of 3D optical medical imaging devices.

Optical Medical Imaging

Ongoing
We advance measurement science and standards infrastructure to accelerate adoption of optical medical imaging technologies for surgical and clinical applications. Optical medical imaging promises to enhance and complement conventional medical imaging modalities that include magnetic resonance

Quantum State-Resolved Spectroscopic Techniques

Ongoing
Terahertz radiation interrogates the lowest frequency vibrational (phonon) modes of biomolecules. These modes characterize the incipient motions for large-scale conformational changes responsible for the backbone flexibility of protein, polynucleotide and polysaccharide. Thus, terahertz spectral

THz Detection of Corrosion on Rebar Embedded in Concrete

Ongoing
We developed a new technology to detect and quantify the extent of corrosion in embedded rebar using Terahertz (THz) and microwave spectroscopies. This new method exploits the likelihood that a number of iron corrosion products are antiferromagnetic and absorb THz and microwave radiation. In this
