Photoacoustic Device Probes Tissue with Low-Cost Laser Diodes
INDORE, India, March 5, 2024 — Photoacoustic (PA) technologies offer a noninvasive approach to probing biological tissues, but have seen limited use in clinical applications, partially due to bulky, expensive laser sources. A compact photoacoustic (PA) sensing instrument for...
Optoacoustics, AI Monitor Disease in Patients With Diabetics
MUNICH, Dec. 21, 2023 — One complication of diabetes is microangiopathy, a condition affecting the microvascaulature, which affects numerous organs, including the skin. Routine examinations of the skin’s microvasculature could help clinicians better manage diabetes...
Photonic Gas Analysis Probes Upgrades in Sources and Detectors
Mar 3, 2023 — The hunt is on for better gas analyzers, driven by growing demands. For instance, hydrogen sulfide, an industrial byproduct, has a permissible worker exposure limit of 20 ppm in a confined space, according to OSHA. Increasingly stringent emission...
Photoacoustic Device Modulates Single Neurons with High Spatiotemporal Resolution
BOSTON, Aug. 6, 2021 — An instrument developed at Boston University (BU) could advance fundamental knowledge in the field of neuroscience and lead to treatments for neurological diseases. The tapered fiber optoacoustic emitter (TFOE) uses the optoacoustic effect to enable...
Hybrid Approach Enables Ultralow-Loss Integrated Photonics for Lidar
LAUSANNE, Switzerland, July 23, 2020 — Researchers at École Polytechnique Fédérale de Lausanne (EPFL) and Purdue University demonstrated a hybrid approach to on-chip acousto-optic modulation by combining piezoelectric aluminium nitride technology with ultralow-loss...
Noncontact Laser Ultrasound Safely Images Human Tissue
CAMBRIDGE, Mass., Dec. 24, 2019 — MIT engineers have devised an alternative to conventional ultrasound imaging that doesn’t require contact with the body and can be used on patients who may not tolerate a probe on their body, such as infants, burn patients, or patients with...
Photoacoustic Technology Could Revolutionize Cancer Surgery
WATERLOO, Ontario, Oct. 8, 2019 — Researchers at the University of Waterloo in Ontario, Canada, have developed photoacoustic technology that can precisely locate and distinguish all of a cancerous tumor during surgery. This could help ensure that healthy tissue remains intact while...
New Imaging Technique Targets Cholesterol in Arterial Plaque
BELLINGHAM, Wash., and CARDIFF, Wales — Researchers from the University of Toronto (U of T) have developed a cholesterol-detection imaging technique using laser photoacoustics and continuous wave lasers to allow for more timely treatment of atherosclerosis.
Photoacoustic Technique Measures Frequency to Image Structures of Different Scales
TORONTO, March 25, 2019 — A newly developed frequency domain technique for photoacoustic (PA) image formation, developed by a team at Ryerson University and St. Michael’s Hospital, subdivides PA signals into different frequency bands. Called F-Mode, the new technique...
Photoacoustic Approach Uses Lasers to Send Messages
LEXINGTON, Mass., Jan. 25, 2019 — Researchers from the Massachusetts Institute of Technology’s Lincoln Laboratory have demonstrated two laser-based methods to transmit various audio tones and recorded speech at a conversational volume to a person without any type of receiver...
Momentum of Light Drives Elastic Waves with Unique Signatures
KELOWNA, British Columbia, Aug. 21, 2018 — The exact nature of how light interacts with matter is the focus of an international research study including researchers from Brazil and Slovenia and led by professor Kenneth Chau at the University of British Columbia (UBC). The team measured...
Optical Fibers Can Detect Type of Materials Around Them
LAUSANNE, Switzerland, July 31, 2018 — Forward stimulated Brillouin scattering (FSBS), because of its resonating transverse acoustic waves, has the potential to facilitate detections in an optical fiber’s surroundings. Researchers have now demonstrated a technique to measure the...
All-Optical Ultrasound Transducer Could Transform Keyhole Surgeries
LONDON, Dec. 5, 2017 — An optical ultrasound needle has been developed that allows heart tissue to be imaged in real-time during keyhole procedures. The technology was successfully used for minimally invasive heart surgery on pigs, giving a high-resolution view of soft...
Converting Light to Sound Waves Leads to Hybrid Chip for Data Transfer
CAMPERDOWN, Australia, Sept. 22, 2017 — Researchers have demonstrated a way to transfer optical information coherently to an acoustic hypersound wave on a photonic microchip. Optical information is extracted using a reverse process. A coherent buffer can store the photonic information in...
Photoacoustic Technique Can Detect Gases in Minute Amounts
PROVIDENCE, R.I., Aug. 4, 2017 — Using a photoacoustic technique scientists have demonstrated a way to detect trace gases down to concentrations at the parts-per-quadrillion level. Photoacoustic detectors work by zapping a material with a laser tuned to a wavelength that is...
Optoacoustics, 3D Printing Form Sound Fields With Specific Shapes
LONDON, March 17, 2017 — A method for generating ultrasound via light, coupled with 3D printing, has demonstrated the ability to form sound fields with specific shapes, for potential use in biological cell manipulation and drug delivery. This method could provide a simpler,...
Photoacoustics Promising for Cervical Cancer Assessment
CHANGSHA, China, Dec. 30, 2014 — Photoacoustic imaging could one day provide a quicker and less invasive alternative to current methods for detecting cervical cancer. Following a study of 30 cervical tissue samples, researchers at Central South University in China said the...
Handheld Probe Combines Photoacoustics, Ultrasound
ENSCHEDE, Netherlands, Nov. 7, 2014 — A new handheld imaging system that combines photoacoustics and ultrasound produces real-time, detailed images of blood vessels, internal organs and body parts.
Device Spots Deadly Melanoma, Cell by Cell
COLUMBIA, Mo., Jan. 11, 2012 — A tool based on laser-induced ultrasound technology can detect single melanoma cells in a blood sample at a fraction of the cost of current cancer tests. A prototype developed at the University of Missouri’s Bond Life Sciences Center is now poised...
Analyzing Particles to Save the Planet – and for Profit
Mar 1, 2011 — Shane M. Murphy’s research begins with something small but could end with something big. Murphy, a scientist with the National Oceanic and Atmospheric Administration (NOAA) in Boulder, Colo., is interested in airborne aerosols. Along with...
