A team of researchers from UC Irvine, HRL Laboratories and the California Institute of Technology have developed the world's lightest material - with a density of 0.9 mg/cc - about 100 times lighter than Styrofoam.
Integrating a complex, single-crystal material with "giant" piezoelectric properties onto silicon, University of Wisconsin-Madison engineers and physicists can fabricate low-voltage, near-nanoscale electromechanical devices that could lead to improvements in high-resolution 3-D imaging, signal processing, communications, energy harvesting, sensing, and actuators for nanopositioning devices, among others.
Recent studies conducted at Marshall University have demonstrated that nanoparticles of cerium oxide - common diesel fuel additives used to increase the fuel efficiency of automobile engines - can travel from the lungs to the liver and that this process is associated with liver damage.
The metabolism of lung cancer patients is different than the metabolism of healthy people. And so the molecules that make up cancer patients' exhaled breath are different too. A new device pioneered at the University of Colorado Cancer Center and Nobel-Prize-winning Technion University in Haifa, Israel uses gold nanoparticles to trap and define these molecules in exhaled breath.
A team of researchers from the NIST Center for Nanoscale Science and Technology, the University of Muenster, and West Virginia University have demonstrated control of magnetic thermal fluctuations using current.
Professor Dr. Claudia Felser of Johannes Gutenberg University Mainz has been awarded a grant by the European Research Council worth more than 2.4 million euros to further her research into new materials based on Heusler compounds.
Today, during Science Week, CRANN, the SFI-funded nanoscience institute based in Trinity College Dublin, has announced the launch of an innovative educational package, 'Nano in My Life'. The package will introduce Transition Year and Senior Cycle students to nanoscience, the study of materials at very tiny dimensions, which is set to become part of the proposed new Leaving Certificate syllabi.
The event marked the Golden Jubilee of Solid State Physics Laboratory in Dehli, a premier institute of the Defence Research and Development Board, working on development of solid state devices for defence needs.
Researchers have developed an inhalable porous silica nanoparticle that not only delivers potent anticancer drugs only to non-small cell lung tumors, but also delivers agents that prevent the development of drug resistance.
Cancer biologists have long presumed that tumor cells shed telltale markers into the blood and that finding these blood-borne biomarkers could provide an early indicator that cancer is developing somewhere in the body. Now, a research team at the George Mason University has shown that they can fish out the "invisible" proteins masked by albumin and other high concentration proteins using porous nanoparticles decorated with a series of chemical baits, each designed to harvest specific types of trace proteins from body fluids.
Making a tumor more sensitive to radiotherapy is a primary goal of combining chemo and radiation therapy to treat many types of cancer, but with the chemotherapy drugs come unwanted side effects. Now, investigators from the University of North Carolina report what they believe is the first pre-clinical demonstration of the potential of molecularly targeted nanoparticles as a promising new class of agents that can improve chemoradiotherapy treatment.
Scientists developed a method to combine a tumor-homing peptide, a cell-killing peptide, and a nanoparticle that both enhances tumor cell death and allows the researchers to image the tumors. When used to treat mice with glioblastoma, this new nanosystem eradicated most tumors in one model and significantly delayed tumor development in another.
Using magnetic nanoparticles as a sensitive readout of drug targeting, and a miniaturized nuclear magnetic resonance instrument, researchers created a novel system for directly measuring both target expression and drug binding in a small number of tumor cells obtained via needle biopsy.
