Microscopic magnetic probes that change shape in response to their environment may greatly enhance magnetic resonance imaging (MRI). However, producing the
Researchers at NIST and their colleagues have built a superconducting camera containing 400,000 pixels — 400 times more than any other device of its type.
The purpose of this human subjects study is to collect high-quality measurements of the reflectance spectrum of human skin and assess the variability across the
The most commonly used cell-based assays for measuring cytotoxicity often show poor reproducibility, require 24 h to complete, and rely on a nonspecific
The Quantitative MRI project develops calibration structures (phantoms) and validates quantitative imaging protocols for magnetic resonance imaging (MRI)
As part of the NIST on a Chip program, the Photonic Dosimetry project is developing in-situ sub-micrometer ionizing-radiation dosimetry and calorimetry leading
