Compact Biosensor Offers Continuous Detection of Environmental Estrogens
GUANGZHOU, China, Oct. 5, 2021 — A plasmonic optical fiber biosensor, developed by researchers at Jinan and Tsinghua universities, uses light-matter interaction and advanced surface chemistry to achieve ultrasensitive detection of environmental estrogens (EEs). The compact, flexible biosensor is portable and easy to implement. It could be used to detect endocrine disruptors in remote locations and spaces that are hard to reach. The biosensor platform is based on a gold-coated tilted fiber Bragg grating (TFBG). The TFBG
Laser-Powered Nanomotors Follow Their Path
TOKYO, Nov. 4, 2020 — Researchers from the Institute of Industrial Science at the University of Tokyo have designed linear nanomotors that can be made to move in controlled directions by laser light. The technology has applications in microfluidics, including...
Plasma Scattering Microscopy Allows Precise Imaging of Individual Proteins
TEMPE, Ariz., Sept. 22, 2020 — Researchers at Arizona State University have developed a microscopy technique that harnesses surface plasmon resonance (SPR) to enable precision imaging of individual proteins. SPR has been used to investigate the interactions of bacteria and...
Quantum-Enhanced Plasmonic Sensing Could Improve Biosensing, Chemical Detection
NORMAN, Okla., May 21, 2018 — Researchers used quantum states of light to enhance the sensitivities of plasmonic sensors. Results of the experiment could lead to enhanced ultratrace label-free plasmonic sensing for a range of applications. Plasmonic sensors have been shown to...
Nanosensors on CDs Simplify Bio Sample Study
MADRID, March 17, 2014 — CD players have been overshadowed by mp3 files in the entertainment world, but in the biology lab, they could be the wave of the future.
Plasmonics boosts performance in polymer LEDs, solar cells
Oct 1, 2013 — Using carbon-dot-supported silver nanoparticles to produce a surface plasmon resonance effect can boost the performance of both polymer LEDs (PLEDs) and polymer solar cells (PSCs) while keeping their structure simple. Most semiconducting...
Low-Cost SPR Services Offered in Colorado
BOULDER, Colo., July 23, 2013 — BiOptix has announced a partnership with the University of Colorado at Denver to offer low-cost surface plasmon resonance (SPR) services to Colorado-based researchers in academia and industry.
Plasmonics Gives Performance Boost to Polymer LEDs, Solar Cells
ULSAN, South Korea, July 23, 2013 — A new plasmonic material based on carbon dot-supported silver (CD-Ag) nanoparticles, which produce a surface plasmon resonance effect, has boosted the performance of polymer LEDs (PLEDs) and polymer solar cells (PSCs) while keeping their structure...
Optical Sensors Watch What We Eat
Jun 1, 2013 — Optics technologies are advancing food safety applications. Natural pathogens. Food fraud and adulteration. Bioterrorism. Food safety is more of a concern today than it’s ever been before. Because the path from producer to consumer is...
Polymer Solar Cell Efficiency Hits 8.9 Percent
ULSAN, South Korea, May 8, 2013 — The highly purified silicon crystal used in today’s commercial solar cells could be replaced with more economical, disposable, polymer-based materials if their efficiency and stability could be improved. A team at Ulsan National Institute of...
BiOptix Expands into Surface Plasmon Resonance
BOULDER, Colo., May 3, 2012 — To promote its expansion into the surface plasmon resonance marketplace, the privately held analytical biosensor instrumentation company unveiled its new corporate brand identity and tagline: “Kinetics with Confidence.”
Simpler, more cost-effective biosensing
GÖTEBORG, Sweden – There are two challenges facing optical label-free biosensing, especially for clinical applications, according to Alexandre Dmitriev of Chalmers University of Technology.< “The system should be able to work in physiological fluids –...
Evotec, Active Biotech Ink Screening Pact
HAMBURG, Germany, March 22, 2010 – Evotec AG announced it has entered into a collaboration with Active Biotech AB to identify small-molecule modulators of a priority biological target, selected by the latter company...
Golden Bullet Targets Cancer
ST. LOUIS, March 15, 2010 – The mythological silver bullet has just been turned gold. A highly targeted medical treatment, known as the silver bullet, the magic bullet or the Zuberkugel, has become a focu...
Seeing Smaller Features with Surface Plasmons
May 1, 2007 — Imaging using surface plasmon resonance — electron oscillations induced by light at a metal/dielectric interface — can reveal hidden features such as minute changes in biochemical structures. However, surface plasmon resonance imaging can be fuzzy...
