A field full of pyramids, but on a micro scale. Each of the pyramids hides a living cell. Thanks to 3D micro- and nano scale fabrication, promising new applications can be found. One of them is applying the micro pyramids for cell research: thanks to the open ‘walls’ of the pyramids, the cells interact. Scientists of the research institutes MESA+ and MIRA of the University of Twente in The Netherlands present this new technology and first applications in Small journal of the beginning of December.
Scientists at Imperial College London have developed a system to quickly detect trace amounts of chemicals like pollutants, explosives or illegal drugs.
New research at King's College London may lead to improved solar cells and LED-displays. Researchers from the Biophysics and Nanotechnology Group at King's, led by Professor Anatoly Zayats in the department of Physics have demonstrated in detail how to separate colours and create 'rainbows' using nanoscale structures on a metal surface. The research is published in Nature's Scientific Reports.
Scotch tape, a versatile household staple and a mainstay of holiday gift-wrapping, may have a new scientific application as a shape-changing "smart material."
Researchers at Wake Forest Baptist Medical Center have modified electrically-conductive polymers, commonly used in solar energy applications, to develop revolutionary polymer nanoparticles (PNs) for a medical application. When the nanoparticles are exposed to infrared light, they generate heat that can be used to kill colorectal cancer cells.
In the first-ever experiment of its kind, researchers have demonstrated that clean energy hydrogen can be produced from water splitting by using very small metal particles that are exposed to sunlight. In the article, “Outstanding activity of sub-nm Au clusters for photocatalytic hydrogen production,” published in the journal Applied Catalysis B: Environmental, Alexander Orlov, PhD, an Assistant Professor of Materials Science & Engineering at Stony Brook University, and his colleagues from Stony Brook and Brookhaven National Laboratory, found that the use of gold particles smaller than one nanometer resulted in greater hydrogen production than other co-catalysts tested.
In a world-first, researchers from UNSW’s Australian Centre for Nanomedicine have developed a nanoparticle that improves the effectiveness of chemotherapy for neuroblastoma by a factor of five.
Serendipity proved to be a key ingredient for the latest nanoparticles discovered at Rice University. The new "lava dot" particles were discovered accidentally when researchers stumbled upon a way of using molten droplets of metal salt to make hollow, coated versions of a nanotech staple called quantum dots.
The International Center for Materials Nanoarchitectonics, National Institute for Materials Science announced that it will host a symposium for high school students as a joint project of Japanfs 6 WPI research centers.
Working in the lab for the last few years, three generations of University of Akron polymer scientists say their mutual and passionate curiosity about science has led to their discovery of a first-of-its-kind, easily adaptable biocompatible polymer structure able to fight infection, filter water and perform a host of other functions.
