Order tends towards disorder. This is also true for quantum states. Measurements at the Vienna University of Technology show that in quantum mechanics this transition can be quite different from what we experience in our daily lives.
In experiments mimicking a natural environment, Duke University researchers have demonstrated that the silver nanoparticles used in many consumer products can have an adverse effect on plants and microorganisms.
The newly-developed double switchable membranes could make it possible, in future, to filter different biomolecules, e.g. hormones, proteins, nucleic acids (DNA), according to pore size. This opens up a further possible field of application, in addition to water purification, in the field of medicine e.g. for blood purification.
Bioengineering researchers at University of California, Santa Barbara have found that changing the shape of chemotherapy drug nanoparticles from spherical to rod-shaped made them up to 10,000 times more effective at specifically targeting and delivering anti-cancer drugs to breast cancer cells.
Researchers at Rice University and Sandia National Laboratories have made a nanotube-based photodetector that gathers light in and beyond visible wavelengths. It promises to make possible a unique set of optoelectronic devices, solar cells and perhaps even specialized cameras.
From November 20th for two days, BHR Group will bring together global nanotechnology experts, academics, and industrial consumers of nanotechnology to discuss industrial processes for nano materials and particles.
Millions of tons of still-edible food are thrown away because the "best before" date has passed. Wouldn't it be handy if the packaging could really "test" whether the contents are still safe to eat? Researchers have invented a circuit that makes this possible: A plastic analog-digital converter. This brings plastic sensor circuits costing less than one euro cent within reach.
The organizers of ImagineNano announced France as the Invited Country at this year's edition. Forty French invited speakers among 7 conferences and a pavilion featuring the nanoscience and nanotechnology sector in this country are some of the activities planned.
