Plasmon-powered upconversion nanocrystals for enhanced bioimaging and polarized emission

ScienceDaily.com: Nanotechnology News - 19 мая, 2017 - 15:36
Rare-earth-doped nanocrystals have become sought-after materials for cellular bioprobes because of their long emission lifetimes and low cytotoxicity. Researchers have now discovered how to make these probes even brighter by coupling them to gold nanorods materials that can induce field-enhanced fluorescence through surface plasmon resonances. They optimized this effect by systematically varying the thickness of a protective silica coating sandwiched between the gold nanorods and the doped nanocrystals.

Sensors detect disease markers in breath

Nanowerk.com - 18 мая, 2017 - 22:00
A small, thin square of an organic plastic that can detect disease markers in breath or toxins in a building's air could soon be the basis of portable, disposable sensor devices. By riddling the thin plastic films with nanopores, researchers made the devices sensitive enough to detect at levels that are far too low to smell, yet are important to human health.

Deconstructing osmosis provides insight for medical and industrial use

ScienceDaily.com: Nanotechnology News - 18 мая, 2017 - 21:02
New research into osmosis-driven behavior now provides a more granular theoretical understanding of the deterministic mechanisms, report scientists in two new papers. The first paper deconstructs the molecular mechanics of osmosis with high concentrations, and generalizes the findings to predict behavior for arbitrary concentrations. The second piece of the study then simulates via molecular modeling two key forms of osmotic flow in a broadly utilizable way.
