Computational Method for Detecting and Enhancing Protein Dynamics ORNL researchers have developed a method that uses simulation and experimental data to detect, analyze, and manipulate protein activity. This approach enables enhancement of the chemical reaction rates of enzymes by many orders of magnitude. More efficient enzymes are widely sought for applications in the biochemical industry, phar…

Standoff Detection of Chemicals Using Rydberg Fingerprint Spectroscopy and Microwave Rayleigh Scattering The invention relates to a method for standoff trace chemical sensing. The basis for the technique is Rydberg Fingerprint Spectroscopy followed by microwave-based detection. In Rydberg Fingerprint Spectroscopy, target molecules are first excited to a Rydberg state (usually 3s) and then pass t…

An Intrusion Detection System Using Quantum-Mechanical Systems Securing property and communication boundaries is critical for sensitive sites like nuclear and chemical facilities and military bases, as well as other places where valuable goods are stored. ORNL researchers used a quantum mechanics approach to develop a device that detects intrusion across a physical boundary or communication links…

Low-cost, Rapid DNA Sequencing Technique A faster, less expensive, more accurate and more reliable method for DNA sequencing has been developed at ORNL. The method takes a high-frequency measurement on a single strand of DNA or RNA deposited on a substrate using an alternating current (AC). The data is used as a criterion to identify the genetic sequence. Sequencing DNA is crucial for future br…
