As a follow-up of the establishment of a Memorandum of Understanding between the European Commission's Joint Research Centre, Institute for Health and Consumer Protection and the Chinese Academy of Inspection and Quarantine (CIAQ), signed in June 2010, the first Sino-EU Symposium on nanotechnology in consumer products was held on 14-15 April 2011 in Beijing.
The P3SENS consortium has been formed to develop an immunoassay detection device suitable for use in emergency-medicine, whether diagnosis is required in an ambulance, emergency room or as part of a rapid near-patient laboratory test in a hospital environment.
Researchers have now deciphered how one of the intracellular transport complexes from yeast cells recognizes its cargo mRNA and initiates assembly. The new findings might also be applicable to higher organisms, where transport processes are especially critical for cell function.
There is currently no cure for retinitis pigmentosa, but scientists are working on ways to restore vision by making other cells of the retina, which are spared by the disease, sensitive to light. In a new study of mice, researchers at the University of Southern California (USC) used technology developed by a consortium of institutions, including MIT, to do just that. By inducing light sensitivity in other cells of the retina, they brought back enough vision for the mice to navigate a maze.
The flat surface of a silicon wafer is not smooth at all. Scientists of the EU research project Pronano have built a new tool that allows them to visualise the nano-scale of it. And now the smooth surface looks like a mountain range.
Researchers have found theoretically that a regular lattice of Skyrmions, whose role in solid state systems such as ferromagnets has been attracting great interest, can form in a thin confined liquid crystal, a system completely different from solid state systems.
Chemotherapy drug resistance contributes to treatment failure in more than 90 percent of metastatic cancers. Overcoming this hurdle would significantly improve cancer survival rates. Dean Ho, of Northwestern University, believes a tiny carbon particle called a nanodiamond may offer an effective drug delivery solution for hard-to-treat cancers.
The effectiveness of optical imaging processes can be significantly improved with suitable dyes used as contrast agents. Now, researchers have introduced a novel contrast agent that marks tumor cells in vitro. The dye is a phosphorescent ruthenium complex incorporated into nanoparticles of a metal-organic coordination polymer, which allows an extraordinarily high level of dye loading.
A multidisciplinary team of investigators at Harvard and MIT have created a new device that can detect single cancer cells in a blood sample, potentially allowing doctors to quickly determine whether cancer has spread from its original site. The microfluidic device is about the size of a dime, and could also detect cancer-causing viruses such as hepatitis B and C and the human papilloma virus.
Yu Huang, an assistant professor of materials science and engineering at the UCLA Henry Samueli School of Engineering and Applied Science, and her research team have proposed and demonstrated a new approach to producing nanocrystals with predictable shapes by utilizing surfactants, biomolecules that can bind selectively to certain facets of the crystals' exposed surfaces.
Researchers at the University of California, Santa Barbara, say they've figured out the cause of a problem that's made light-emitting diodes (LEDs) impractical for general lighting purposes. Their work will help engineers develop a new generation of high-performance, energy-efficient lighting that could replace incandescent and fluorescent bulbs.
Using well-known patterned media, a team of researchers in France has figured out a way to double the areal density of information by essentially cutting the magnetic media into small pieces and building a "3D tower" out of it
