Researchers Develop High-Precision Dual-Color Optogenetic Brain Probe
AMHERST, Mass., Dec. 26, 2023 — Optogenetics promises to manipulate brain circuitry by exciting or inhibiting neurons with different wavelengths of light. Until now, neural probes have largely been limited to single colors, only capable of either excitation or inhibition. Probes...
Lensless Camera Captures Cellular-Level Details in 3D
HOUSTON, March 18, 2022 — Rice University researchers have tested a tiny lensless microscope called Bio-FlatScope, capable of producing high levels of detail in living samples. The team imaged plants, hydra, and, to a limited extent, a human. A previous iteration of the...
Microscopy Method Enables Deep In Vivo Brain Imaging
HEIDELBERG, Germany, Oct. 4, 2021 — A method developed by the Prevedel Group at the European Molecular Biology Laboratory (EMBL) allows neuroscientists to observe live neurons deep within the brain — or any other cell hidden within an opaque tissue. The method is based on...
Chromium Complex Emits Light in the Coveted NIR-II Range
BASEL, Switzerland, Aug. 17, 2021 — A team of Swiss scientists has developed the first chromium complex that emits light in the NIR-II (1000 to 1700 nm) range. The scientists achieved an NIR-II luminescence of 1067 nm by strengthening the metal-ligand bond covalence in the complex....
STED Microscopy Calibration Method Improves Brain Imaging
BORDEAUX, France, June 21, 2021 — Researchers from the University of Bordeaux have found a way to calibrate stimulated emission depletion (STED) microscopy for improved brain imaging. The method increases the depth at which STED microscopy can image and be applied to other tissues....
The Shape of Light Restructures Our Understanding of Vision
GENEVA, April 29, 2021 — Recent work has shown that the process involving the perception of vision occurs very quickly. However, because analysis of this step has been carried out on molecules in a laboratory environment, only limited conclusions can be drawn. Now,...
Pseudo-Random Speckle Illumination Patterns Allow for High-Resolution Imaging
TOKYO, Feb. 6, 2020 — Researchers at the University of Tokyo have demonstrated the use of a multimode fiber (MMF) in combination with an integrated optical phased array (OPA) chip for single-pixel imaging in potential biomedical applications. The technology could allow...
Tohoku, Advantest Develop In Vivo Skin Imaging Technology
TOKYO, Nov. 26, 2018 — An R&D group led by Professor Yoshifumi Saijo of Tohoku University and Noriyuki Masuda of Advantest Europe GmbH has succeeded in developing in vivo skin imaging technology that can simultaneously generate dual-wavelength photoacoustic images and...
Hyperspectral Imager Boosts Biomed Research
NEWTON, Mass., March 14, 2014 — A new hyperspectral imaging system offers identification and analysis of complex microscopic samples in real time.
PerkinElmer Acquires VisEn
WALTHAM, Mass., Aug. 4, 2010 — PerkinElmer Inc. announced it has acquired VisEn Medical Inc. of Bedford, Mass., an in vivo molecular imaging technology company. The acquisition has enabled the company that focuses on the health and safety of people and the environment to enhance...
Endra Launches Imaging System
ANN ARBOR, Mich., April 21, 2010 — Endra Life Sciences has announced the launch of the Nexus 128, a photoacoustic computed tomography scanner for small animal imaging. The system is used for simple, fast and noninvasive quantification of tumor vasculature and other physiological...
Multibeam Lasers Emit in IR
CAMBRIDGE, Mass., Nov. 30, 2009 – An international team of applied scientists demonstrated compact, multibeam and multiwavelength lasers emitting in the infrared. Typically, lasers emit a single light beam of a well-defined wavelength; with their multibeam abilities, the new lasers...
Glycominds Joins Biomolecular Photonic Consortium
Sep 27, 2007 — Biodiagnostics company Glycominds Ltd. of Lod, Israel, maker of a blood test for detecting inflammatory bowel disease and the severity of Crohn's disease, announced this week it has joined the Biomolecular Photonic (BMP) Consortium. "Glycominds'...
Big Mac Ingredient Stabilizes Gold Nanoparticles
COLUMBIA, Mo., Feb. 27, 2007 -- Researchers have discovered that gum arabic, a plant extract used to stabilize foods such as Big Macs, yogurt and soda, can be used to absorb and assimilate metals and create a "coating" that makes gold nanoparticles safe for nanomedicine...
High-Res Scan Reveals Cartilage in 3-D
ATLANTA, Dec. 5, 2006 -- By combining two existing technologies, researchers have created a new noninvasive, high-resolution way to image cartilage. The technique shows promise in research on the progression and treatment of osteoarthritis, a common degenerative...
New MRI Technique is Ultrasensitive
BERKELEY, Calif., Oct. 25, 2006 -- A new technique for magnetic resonance imaging (MRI) that allows the detection of signals from molecules present at 10,000 times lower concentrations than conventional MRI could prove valuable for medical diagnosis, and has the potential to one day...
