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 ...
Chemically assembled metamaterials may lead to superlenses
(PhysOrg.com) -- Nanomanufacturing technology has enabled scientists to create metamaterials -- stuff that never existed in nature -- with unusual optical properties. They could lead to "superlenses" able ...
Breakthrough furnace can cut solar costs
(PhysOrg.com) -- Solar cells, the heart of the photovoltaic industry, must be tested for mechanical strength, oxidized, annealed, purified, diffused, etched, and layered.
Tagging tumors with gold: Scientists use gold nanorods to flag brain tumors
"It's not brain surgery" is a phrase often uttered to dismiss a job's difficulty, but when the task actually is removing a brain tumor, even the slightest mistake could have serious health consequences. To ...
Nanowire lens can reconfigure its imaging properties
Twisted crystals point way toward active optical materials
(PhysOrg.com) -- A nanoscale game of "now you see it, now you don't" may contribute to the creation of metamaterials with useful optical properties that can be actively controlled, according to scientists ...
Good vibrations for future quantum computers
