Wearable Sensors Challenge Traditional Medical Technology
Dec 4, 2018 — From Apple to Fitbit to Garmin to Google, in the U.S. alone, dozens of companies are producing wearable sensors that record our movements as well as basic health information. Many of these devices rely on optical telemetry to read information about the body and transmit it to a smartphone via Bluetooth or Wi-Fi. While the growth of the smartphone market may be leveling off — in part because users are keeping their devices longer — the wrist and body are still prime, underexplored

OLED Surpasses 100 Percent Exciton Production Efficiency
FUKUOKA, Japan, July 10, 2018 — In a new approach to improving OLED efficiency, researchers are using singlet fission to split the energy of one exciton in two. This approach has made it possible for the team to exceed the 100 percent limit for exciton production efficiency in...
Evolution of the Supercontinuum Light Source
Nov 28, 2017 — For many applications, coherent light at a single frequency is more than adequate. But having a light source that combines the properties of a laser with the broad bandwidth of an incandescent bulb and a short pulse duration opens up a new realm of...
Nanosensors Used to Track Progression of Obesity-Related Diseases
KINGSTON, R.I., October 6, 2017 — According to a New England Journal of Medicine study, more than one third of the world's population is overweight or obese. And, these weight issues can often lead to other health concerns. Researchers from the University of Rhode Island, the...
Diagnostic Tool Uses NIR to Detect Risk of Heart Attack, Stroke
COVENTRY, England, and MELBOURNE, Australia, Aug. 21, 2017 — Scientists increased the wavelength in a tool used to detect fatty deposit build-up in arteries to NIR wavelengths, and found that they could use the tool to selectively identify plaques with internal bleeding typically associated with high-risk...
Laser Ablation System Enables Transdermal Drug Delivery
KUMAMOTO, Japan, Aug. 17, 2017 — A novel transdermal protein delivery system for protein-based drugs uses photothermal ablation to increase the permeability of the skin by heating and perturbing the first skin layer, so that the drug can be delivered through via a skin patch....
Lasers Zap Toxic French Fries
May 5, 2017 — “Lasers and french fries” doesn’t have the same ring as “hamburgers and french fries,” or even “ketchup and french fries,” but the strange combination could make the fast food a little safer when it hits the...
Optical Sensors Advancing Precision in Agricultural Production
May 1, 2017 — Agricultural production, already incredibly efficient in much of the developed world, is increasing each year — this is a necessity to feed the 9+ billion people expected on the planet by 2050. A great example of productivity gains is in corn...
Panasonic Develops Electric Control of Light Sensitivity
OSAKA, Japan, Feb. 23, 2017 — Electronics developer Panasonic Corp. has developed electrical control of NIR light sensitivity of the same pixel in an organic CMOS image sensor. The sensitivity of all the pixels in the image sensor, which has directly stacked organic films, is...
Global Spectroscopy Market Set to Expand
Jan 6, 2017 — The global spectroscopy market continues on its rise toward the billion dollar zone. With increasing applications in pharmaceuticals and the life sciences, as well as some in industrial settings and food safety, the market is witnessing steady...
Light Could Restore Health in Bees Exposed to Pesticide
LONDON, Nov. 16, 2016 — Near-IR light therapy has been shown to counteract the harmful effects of neonicotinoid pesticides and improve survival rates of poisoned bees.
FS Pulses in Mid-IR Wavelengths Could Reveal Inner Workings of Atoms
CAMBRIDGE, Mass., Nov. 1, 2016 — A laser pulse synthesizer with the ability to attain ultra- short pulses in the mid-IR range while maintaining favorable energy scalability could provide scientists with a more complete view of the inner workings of atoms, molecules and solids. For...
NIR Light Upregulates CCO, Stimulates Blood Flow
ARLINGTON, Texas, Sept. 15, 2016 — Broadband NIRS has potential as a non-invasive, in vivo means to study mechanisms of photobiomodulation and perform treatment evaluations of low-level laser/light therapy (LLLT). In a placebo-controlled study, researchers at the University of Texas...
Giacobazzi Appointed President of Deposition Sciences
SANTA ROSA, Calif., Aug. 29, 2016 — Optical thin film filter coating developer Deposition Sciences Inc. has announced the appointment of James Giacobazzi as its new president. Giacobazzi brings more than 15 years of executive management experience in advanced technology companies. He...
Plasmonic Nanoheaters Enable Photothermal Cancer Therapy
COPENHAGEN, Denmark, Aug. 8, 2016 — In vitro and in vivo studies have positively correlated the heat generation of plasmonic nanoparticle with their potential as cancer-killing agents. Using a single-particle and positron emission tomography (PET)-based platform, researchers from the...
Cancer Treatment Combines Phototherapy with Drug, Gene Therapy
CAMBRIDGE, Mass., Aug. 2. 2016 — A cancer treatment that combines light-based, drug and gene therapy has led to complete tumor remission when applied to non-resected tumors and to the absence of tumor recurrence when applied following tumor resection in a colon cancer mouse model....
Compound Transforms IR into Broadband White Light
MARBURG, Germany, June 21, 2016 — A compound that can transform near-infrared (NIR) light into broadband white-light could offer a cheap, efficient means to produce visible light. The light is also exceedingly directional, a desirable quality for devices such as microscopes that...
Mauna Kea Miniprobe Receives FDA Clearance
PARIS, June 2, 2016 — Microscopy developer Mauna Kea Technologies SA has received its twelfth 510(k) clearance from the U.S. Food and Drug Administration (FDA). The new FDA clearance covers its confocal miniprobes for use in urological and minimally-invasive surgical...
Precise Wavelength Used to Gently Image Lungs of Newborns
LUND, Sweden, April 6, 2016 — To avoid the harmful radiation resulting from x-rays, near-infrared (NIR) spectroscopy has been used to image oxygen concentrations in the lungs of newborns, a technique that could be used to noninvasively monitor premature babies with...
Application Note: NIR Spectroscopy Aids Diagnosis of Neonatal Brain Injury
LONDON, Jan. 15, 2016 — A near-infrared (NIR) spectroscopy system has been used to measure cerebral changes and oxygen utilization in vivo, offering a noninvasive diagnostic technique for neonatal brain injury. Researchers from University College London, the Institute for...
Laser Measurements Simplify Electronics Testing
BRAUNSCHWEIG, Germany, Dec. 26, 2015 — Femtosecond lasers may provide a cost-effective alternative to conventional vector network analyzers for high-frequency measurements involved in electronics testing. Researchers at Physikalisch-Technische Bundesanstalt (PTB) carried out such...
Application Note: Portable NIR Spectroscopy System Authenticates Textiles
NEWARK, Del., Dec. 25, 2015 — A portable near-infrared (NIR) spectrometer characterizes the fiber content of textiles, an application that could be used to identify counterfeit materials without having to send samples to a laboratory. Traditionally, textiles are analyzed via...
