U.S. FDA clears optical sensor for noninvasive blood flow monitoring

The noninvasive optical sensor addresses a critical unmet need for vascular specialists who are seeking improved methods to detect and measure treatment efficacy for peripheral artery disease.

The Aurora advanced flow cytometry system from Cytek Biosciences.

Fluorescence-based flow cytometry platform achieves 40 colors

The Aurora flow cytometer is available with up to five lasers to enable analyzing up to 40 markers simultaneously in one sample.

Rice graduate student Bo Jiang shows a fluorescing vial of soluble amyloid beta peptide aggregates implicated in the onset of Alzheimer’s disease. The peptides are tagged and tracked with a ruthenium complex developed at Rice University that can monitor them in lab experiments as they grow over time.

Fluorescence monitors how protein aggregate present in Alzheimer's grows

Using a fluorescence method, researchers have found a way to track the formation of soluble amyloid beta peptide aggregates implicated in the onset of Alzheimer's disease.

Artificial intelligence improves OCT image analysis of the eye

Researchers applied artificial intelligence deep learning techniques to develop a more accurate and detailed method for analyzing optical coherence tomography (OCT) images of the back of the eye.

Silver nanopillars from laser simulation are shown.

Biocompatible nanolaser has ability to function inside living tissues

The nanolaser, mainly made of biocompatible glass, shows promise for imaging in living tissues.

Dr. Clare Manderson with the laser incubation technology.

Laser incubator for blood cuts down testing time before a blood transfusion

The development could prevent fatal blood transfusions in critically ill patients, and can detect antibodies in pregnant women that can kill a fetus.

Scientists have used a microchip to map the back of the eye for disease diagnosis; here, technical obstacles have been overcome to fabricate a miniature device able to capture high-quality images.

Novel microchip has goal of miniaturized OCT imaging

The research team developing the microchip demonstrated its ability to produce high-contrast optical coherence tomography (OCT) images 0.6 mm deeper in human tissue.

A Chromacity laser is shown in operation.

Project to develop streamlined laser setup for deep tissue analysis

The Deep Tissue project has the goal of designing a laser setup that aims to enable greater analysis of biological tissue, including skin, bone, and plant life.

Teledyne Princeton Instruments' BLAZE spectroscopy CCD camera was used in the research team's experiments.

Spectroscopic imaging technique enables high-speed, label-free living cell study

For the spectroscopic imaging experiments, Kano's research group used a spectroscopy CCD camera with super-deep-depletion CCD to yield high near-infrared quantum efficiency.

Flexible and transparent bracelet that uses graphene to measure heart rate, respiration rate, and blood pulse oxygenation continuously.

Flexible, transparent wearable health monitors track multiple vital signs

Rice University chemist Han Xiao and his colleagues have discovered a simple method to turn fluorescent tags on and off with visible light by switching one atom.

Novel probe turns fluorescent dyes for bioimaging on and off—on demand

This image of three worms illustrates functional mosaicism in action. The worms have been genetically modified to express a fluorescent protein that appears as colorful glowing dots. The worm on the left shows fluorescence in every cell. In the middle worm, intestinal cells do not fluoresce because a protein that blocks the fluorescent gene has caused RNA interference (RNAi). In the worm on the right, scientists have removed the enzyme previously believed to be responsible for RNAi in intestinal cells, but fluorescence remains blocked in some of those cells, suggesting that RNAi is being carried out by another enzyme.

Fluorescence methods discover what helps certain cells to evade drug therapy

The high-density diffuse optical tomography system with 158 sources (red) and 166 detectors (cyan) shows the surface of the brain in pink and blue (a); a histogram of brain surface depth across 24 subjects (b) with brain surface depth probability distribution for each subject (c) are also shown. The red stars mark the maximum probability for each subject, while the red line is the most probable depth across all subjects (12.5 mm), highlighting the need of improving both image quality and spatial resolution.
