Display Resolution Increases by 3D-Printing Quantum Dot Nanopixels
CHANGWON, South Korea, Aug. 19, 2020 — A display technology developed at the Korea Electrotechnology Research Institute (KERI) produces 3D pixels with nanoscale dimensions by 3D-printing quantum dots (QDs) embedded in polymer nanowires. The technology — called “nanophotonic 3D printing” by the research team — could be used to achieve superhigh-resolution displays in TVs, smartphones, virtual reality headsets, and other devices. The more pixels on a display screen and the more densely the pixels are
Photonic Instruments, Components Driving (and Steering) NASA’s Mars Rover
Aug 19, 2020 — Numerous photonic devices and applications are contributing to the pursuit of microbial life on Mars, or, more accurately, the quest to determine if, among other novel possibilities, such lifeforms once inhabited the Red Planet. Among the hundreds...
Superresolution Microscopy Images Common Alzheimer’s Protein
LEUVEN, Belgium, July 21, 2020 — As superresolution microscopy has advanced, so too has scientists’ ability to dive deep into the neural network and the compounds that accumulate in conjunction with a variety of conditions. And a team at the VIB-KU Leuven Center for Brain...

Dye Boosts Bioimaging Capability
NOTRE DAME, Ind., June 15, 2020 — Fluorescence imaging has been a boon to research and medicine because of its ability to examine affected areas noninvasively. But the dyes used for these purposes have their disadvantages, and as resolution needs have grown stronger, the stakes for...
Imaging Technology Enables Superresolution Inside Whole Cells
WEST LAFAYETTE, Ind., May 11, 2020 — Purdue University researchers have developed a technology that enables 3D superresolution imaging inside whole-cell or tissue specimens. The technology allows scientists to locate the positions of biomolecules inside whole cells and tissues with a...
Virus Testing Kits to Be Developed Using RNA Imaging Technology
BURNABY, British Columbia, March 20, 2020 — A Simon Fraser University (SFU) research team will be using RNA imaging technology it has created to develop coronavirus testing kits. The decision to apply the technology, called Mango, to COVID-19 testing is in response to a funding opportunity...
Scientists Analyze Final Images from Cassini
LANCASTER, England, Jan. 15, 2020 — Toward the completion of its 13-year mission, which ended in September 2017, the Cassini spacecraft performed a set of orbits that brought it closer to Saturn than ever before. By passing over the planet’s polar regions at a low altitude,...
Deep Learning Speeds 3D Microscopic Neuroimaging
AUSTIN, Texas, and SAN DIEGO, Jan. 14, 2020 — Using deep learning techniques, researchers from the Salk Institute have developed a new microscopy approach that could make microscopic techniques used for brain imaging 16 times faster. The researchers trained their deep learning system using data...
Active Thermal Detection Could Broaden Use of Superresolution Techniques
DAEJEON, South Korea, Jan. 10, 2020 — Be it light, sound, or an electromagnetic wave, a probe beam operates the same way — the beam gets sent ahead and a wave of the same nature is reflected back. The absorbed energy is converted to heat, for which there has been no perceived use...
Ghost Imaging Speeds Up Superresolution Microscopy
SHANGHAI, Jan. 6, 2020 — Scientists from the Chinese Academy of Sciences have developed a new imaging technique that produces nm-scale resolution using significantly fewer images than traditional nanoscopy techniques. The scientists used ghost imaging to enhance the imaging...
New Molecule Marker Enables ‘Unprecedented’ Study of Mitochondria
NAGOYA, Japan, Oct. 23, 2019 — A team at Nagoya University’s Institute of Transformative Bio-Molecules has developed a marker molecule that bypasses the problem of photobleaching in STED microscopy. It’s allowing an unprecedented view of live mitochondria, which could help...
