Laser Speckle Method Captures Blood Flow in Microvasculature
SINGAPORE, March 28, 2022 — Researchers at the National University of Singapore developed a confocal laser speckle autocorrelation method to image dynamic flow in microvasculature. The technique is label-free and enables real-time and quantitative imaging of blood flow on the microscopic level. The system shares many characteristics of a confocal fluorescence microscope; like the confocal fluorescence microscope, it is able to obtain high-quality, detailed flow images from thick tissue samples. The method described
Fluorescent Dye-Based Device Could Help Prevent Tooth Decay
SEATTLE, March 24, 2022 — An optical device in development at the University of Washington (UW) could help prevent tooth decay by identifying at-risk teeth before cavities have had a chance to start to develop. The prototype, called O-pH, uses a low-power light system and an...

Three-Photon Microscopy Reveals Immune Cell Behavior in Real Time
ITHACA, N.Y., Feb. 10, 2022 — A research group from Cornell University has used three-photon microscopy to image the full depth of the popliteal lymph node in a living mouse — reportedly for the first time. The researchers successfully observed the dynamic interactions of...
Hyperspectral Imaging Company Specim Opens US Demo Center
OULU, Finland, Jan. 26, 2022 — Specim opened a demo center at Konica Minolta Sensing US facilities in Ramsey, N.J. The demo center opened this month as a facility to give customers and partners access to hands-on training on Specim products and services. Specim, a developer and...
Chip-size Sensor Performs on Par With Conventional Spectrometers
EINDHOVEN, Netherlands, Jan. 20, 2022 — A miniaturized near-infrared (NIR) sensor for industry, agriculture, and other sectors is ready to be deployed, according to its developers at the Eindhoven University of Technology (TU/e). The sensor’s design is based on an approach to...
Optical Biopsy System Cuts Potential for Misdiagnoses of Liver Cancer
WASHINGTON, D.C., Jan. 18, 2022 — An optical biopsy system that combines diffuse reflectance spectroscopy and fluorescence lifetime measurements can distinguish between cancerous and healthy tissue in the liver. The technology could make it easier to diagnose liver cancer, which is...
Spectroscopy Method Could Raise Number of Viable Donor Kidneys
WASHINGTON, D.C., Jan. 14, 2022 — Researchers at the University of Shanghai for Science and Technology and the Changhai Hospital of Shanghai used label-free surface-enhanced Raman scattering (SERS) spectroscopy to quantitatively assess donor kidney quality, reportedly for the first...
Shift to Transmissive Mode Improves Thick Tissue Laser Speckle Contrast Imaging
WUHAN, China, Jan. 7, 2022 — Although reflective-detected laser speckle contrast imaging (LSCI) is a powerful tool for monitoring blood flow circulation at the surface layers of tissue, it is inadequate for detecting signals from thick tissue layers. A scientific team from...
