Imagine a test that sifts through millions of molecules in a drop of a patient's blood to detect a telltale protein signature of a cancer subtype, or a drug ferry that doesn't release its toxic contents until it slips inside cancer cells. These and other nanotechnologies could be game changers in how we diagnose, monitor and treat cancer. To more fully understand the impact, The Kavli Foundation held a roundtable conference with four pioneers in the field.
Silver nanoparticles cause more damage to testicular cells than titanium dioxide nanoparticles, according to a recent study by the Norwegian Institute of Public Health. However, the use of both types may affect testicular cells with possible consequences for fertility.
Die Kryo-Elektronentomografie ermoeglicht hochaufloesende, dreidimensionale Einblicke in das Innere von Zellen. Jedoch koennen damit nur sehr kleine Zellen oder duenne Randbereiche groesserer Zellern direkt untersucht werden. Wissenschaftler vom Max-Planck-Institut fuer Biochemie haben jetzt eine Methode entwickelt, um in nahezu unzugaengliche Zellbereiche vorzudringen.
A Holy Grail of ultrafast science and technology is to image the changing structure of matter at the nanoscale during the interaction with light. An international collaboration used intense laser pulses delivered by the FLASH free-electron laser for X-ray scattering from nanoparticles. The goal was to look into ultrafast electronic processes during the nanoplasma formation where conventional spectroscopy techniques are inherently blind.
Scientists from the A*STAR Data Storage Institute have demonstrated the viability of fabricating soft magnetic thin films through electrodeposition, a plating technique that is scalable and can be performed at room temperature.
A team of Vanderbilt physicists reports that they have nailed down the source of the interference inhibiting the rapid flow of electrons through graphene-based devices and found a way to suppress it. This discovery allowed them to achieve record-levels of room-temperature electron mobility - the measure of the speed that electrons travel through a material - three times greater than those reported in previous graphene-based devices.
Since January Prof. Dr. Sotiris E. Pratsinis, winner of the award for research of the Alexander von Humboldt Foundation, is visiting scientist at the Universitaet Duisburg-Essen (UDE) from the ETH Zurich, Switzerland.
Two new studies performed at the U.S. Department of Energy's Argonne National Laboratory have revealed a new pathway for materials scientists to use previously unexplored properties of nanocrystalline-diamond thin films.
