Novel nanocrystals with advanced optical properties developed for use as luminescent biomarkers
Upconversion emission materials are ideal for bioimaging due to its effectiveness as contrast agents for the detection of cancer cells, more so when the background emission of non-cancerous tissues can be minimised. These ...
Team develops method for creating 3D photonic crystals
Dutch researchers at the University of Twente's MESA+ research institute, together with ASML, TNO (the Netherlands Organisation for Applied Scientific Research) and TU/e (Eindhoven University of Technology) ...
Manufacturing microscale medical devices for faster tissue engineering
In the emerging field of tissue engineering, scientists encourage cells to grow on carefully designed support scaffolds. The ultimate goal is to create living structures that might one day be used to replace ...
Researchers peer below the surface of living tissue
A fluorescent protein found in Monterey Bay's crystal jellyfish is helping University of California-Santa Cruz scientists peer deeper into living tissue.
New 3-D photonic crystal has both electronic, optical properties
In an advance that could open new avenues for solar cells, lasers, metamaterials and more, researchers at the University of Illinois have demonstrated the first optoelectronically active 3-D photonic crystal.
Historic first images of rod photoreceptors in the living human eye
Scientists today reported that the tiny light-sensing cells known as rods have been clearly and directly imaged in the living eye for the first time. Using adaptive optics (AO), the same technology astronomers ...
Nature of bonding determines thermal conductivity
Optical data carriers such as DVDs, Blu-rays and CD-RWs store data in layers of so-called "phase change materials". In the future, these materials will enable the development of fast, non-volatile and energy-saving main memories. ...
Major advance in understanding how nanowires form
New insights into why and how nanowires take the form they do will have profound implications for the development of future electronic components. PhD student Peter Krogstrup from the Nano-Science Center at ...
Nanotubes behave as optical antennae
(PhysOrg.com) -- Just as walkie-talkies transmit and receive radio waves, carbon nanotubes can transmit and receive light at the nanoscale, Cornell researchers have discovered.
Physicist developing, improving designer optical materials
Advancements in fabrication technologies may lead to superlenses and other designer optical materials, according to an Iowa State University and Ames Laboratory physicist.
Optical surface states in magnetophotonic crystals
Using state of the art microfabrication technology to create periodic structures with high accuracy, Dr Baryshev and colleagues at the Toyohashi University of Technology, Japan, report the existence of so-called ...
Futuristic computing designs inside beetle scales
(PhysOrg.com) -- Though it began as a science fair project involving a shiny Brazilian beetle, Lauren Richey’s research may advance the pursuit of ultra-fast computers that manipulate light rather than electricity.
A pinch of light: Laser 'tweezers' for medicine, communications and harvesting energy
Star Trek fans will remember "tractor beams," lasers that allowed the Starship Enterprise to trap and move objects. Tel Aviv University is now turning this science fiction into science fact -- on a nano scale.
From butterflies' wings to bank notes -- how nature's colors could cut bank fraud
Scientists have discovered a way of mimicking the stunningly bright and beautiful colours found on the wings of tropical butterflies. The findings could have important applications in the security printing ...
