OCT Presents Multidimensional Imaging for Diagnosis and Detection Optical coherence tomography (OCT) is a noninvasive imaging technique that is used to deliver high-resolution images in two or three dimensions. It relies on the wave-like properties of light to...
Liquid Crystal Sensors Provide Rapid COVID-19 Diagnosis The global outbreak of COVID-19 has prompted scientists worldwide to focus their research on the virus over the last year, particularly those who work with optical and sensing technologies. Some have...
Charge Clusters in a Monomeric Protein Alter Optical Absorption Electronic absorption of proteins that lack cofactors, prosthetic groups, or noncoded amino acids as part of their structure has traditionally been thought to originate from protein backbone (peptide...
Quantum Cascade Lasers Boost Life Science Research Over 20 years have passed since the first quantum cascade laser (QCL) sources were commercialized. QCLs that operate at room temperature using thermoelectric cooling are now ubiquitous. These lasers...

Proteins make the invisible visible Changes in the proteins inside a cell may indicate the presence of a particular disease or condition, and these changes have been historically difficult to track. For many years, it was believed that light in the visible range (>320 nm) was not absorbed by proteins, but recent research has shown that this is not the case. Invasive techniques of investigation, such as the injection of...

Fluorescence Microscopy Technique Images Brain at High Resolution A noninvasive brain imaging technique developed by researchers at ETH Zurich and the University of Zurich works in the near-infrared (NIR) spectrum to enable superresolution deep-tissue fluorescence microscopy at four times the depth limit imposed by light diffusion. According to the researchers, the technique, called diffuse optical localization imaging (DOLI), operates in a resolution-depth...
AI-driven Method Developed to Diagnose Neurodegenerative Diseases A combination of OCT, adaptive optics, and neural networks has the potential to enable better diagnosis and monitoring for eye and brain diseases, such as glaucoma, that damage neurons. The...

Flow cytometry standards are needed to ensure effective diagnosis and treatment Flow cytometry is an incredibly powerful technique that has been used for decades to measure the physical and chemical characteristics of populations of cells, constituents of cells, and other small particles of biological and nonbiological origin. As the uses of this technology have expanded, so too has the need for standardization in measurement parameters. In flow cytometry, particles flow in...

Lasers deter birds from salmon run Juvenile salmon traveling in the Columbia River near McNary Dam in Oregon are vulnerable to hungry birds that lurk overhead. Thanks to the Walla Walla District of the Army Corps of Engineers, which deployed lasers in the area, the endangered fish are now protected from above as well as in the water. McNary Dam, maintained by the Corps, stretches 1.4 miles and spans the Columbia River between...
