The International Organization for Standardization (ISO) recently published a Technical Report (TR) that provides guidance on the physicochemical characterization of manufactured nano-objects prior to toxicological assessment.
Inexpensive, portable devices that can rapidly screen cells for leukemia or HIV may soon be possible thanks to a chip that can produce three-dimensional focusing of a stream of cells, according to researchers.
A research group headed by MANA Scientist Dr. Qingmin Ji, in joint research with Prof. Frank Caruso of the University of Melbourne, developed a new elastic capsule using an inorganic nanometer-thickness flake-shaped material.
Researchers of the UPNA-Public University of Navarre have developed a type of coating for construction materials. It is based on nanoparticles that interact with sunlight and trigger a chemical reaction that eliminates certain air pollutants.
The discussion about environmentally friendly regenerative sources of energy and sustainable production and consumption revolves around three aspects of photosynthesis: first, sunlight as an infinite and clean source of energy; second, the conversion and storage of energy in the form of hydrogen and hydrogen-rich carbon compounds; third, the production of food for earth's growing population.
A team of surface scientists has managed to fix single gold atoms on special sites of an iron-oxide surface. This could open the door to more efficient catalysts, requiring less of the precious material.
Super Tiny Giraffe is UC Riverside graduate student Shaahin Amini's entry for the "Science as Art" competition, sponsored by the MRS (Materials Research Society). The photos are of a mix of nickel, aluminum and carbon viewed through a high-powered microscope.
A University of Washington mathematician is part of an international team working to understand invisibility and extend its possible applications. The group has now devised an amplifier that can boost light, sound or other waves while hiding them inside an invisible container.
Duke University chemists created a new set of flexible, electrically conductive nanowires from thin strands of copper atoms mixed with nickel. The copper-nickel nanowires, in the form of a film, conduct electricity even under conditions that break down the transfer of electrons in plain silver and copper nanowires, a new study shows.
Scientists at the Joint Quantum Institute have stored not one but two letters of the alphabet in a tiny cell filled with rubidium atoms which are tailored to absorb and later re-emit messages on demand. This is the first time two images have simultaneously been reliably stored in a non-solid medium and then played back.
The Organic Electronics research group at Linkoping University previously developed ion transistors for transport of both positive and negative ions, as well as biomolecules. They have now succeeded in combining both transistor types into complementary circuits, in a similar way to traditional silicon-based electronics.
Researchers investigated if there was a common underlying mechanism contributing to the development of autoimmune diseases operating at the level of human cells following their exposure to nanoparticles of different nature and possessing diverse physical and chemical properties.
The 8th NanoBio-Europe conference will take place on 18 - 20 June 2012 in Varese (Lombardy, Northern Italy), showcasing the latest international developments in nanobiotechnology, and providing a platform to facilitate interdisciplinary communications, new collaborations for delegates from academic, industrial and clinical backgrounds.
