  • Fibrils, Super Strong Reinforcing Nanomaterials That Are Completely Natural and Made by Trees
    News - 12 Dec 2007
    Their day job is to keep trees upright. But now the forest's tiniest building blocks are on their way into fancy products for the future. Imagine a packaging material that kills bacteria and...
  • Nanoparticle Images and Treats Cancer, Reports on Drug Delivery
    News - 8 Nov 2007
    Using a quantum dot plus an aptamer that doubles as a tether for the anticancer drug doxorubicin, a team of investigators at the Massachusetts Institute of Technology (MIT)-Harvard Center of Cancer...
  • Remote Magnetic Field Triggers Nanoparticle Drug Release
    News - 8 Nov 2007
    Magnetic nanoparticles heated by a remote magnetic field have the potential to release multiple anticancer drugs on demand at the site of a tumor, according to a study published in the journal...
  • Nanotubes Enable New Approach to Cancer Radiotherapy
    News - 23 Aug 2007
    Radioactive elements, or radionuclides, are well-established anticancer agents whose main limitation is that they kill healthy cells almost as easily as they do tumors. But because nanoparticles can...
  • Targeting Quantum Dots To Deliver SiRNA Therapy
    News - 23 Aug 2007
    Take a quantum dot, add a coating of poly(ethylene glycol) (PEG), and attach a homing peptide and a piece of small interfering RNA (siRNA), and the result is a targeted nanoparticle that can stop the...
  • Nanoparticle Combination Therapy Kills Intractable Tumors
    News - 6 Mar 2007
    Administering a small amount of a potent but potentially toxic anticancer agent along with nanoparticles loaded with a second anticancer agent produced a dramatic inhibition of tumor growth in...
  • Targeted Nanoparticles Image Early Tumors
    News - 6 Mar 2007
    A well-established fact in cancer therapy is that early tumor detection improves the odds that a patient will survive the disease. Now, using nanoparticles targeted to the tiny blood vessels that...
  • Quantum Dots Detect Metastatic Lesions
    News - 27 Feb 2007
    By injecting quantum dots into tumors, investigators at Carnegie Mellon University have been able to image sentinel lymph nodes in animals using near-infrared light. These results could lead to a...
  • Carbon Nanotubes Deliver siRNA into Human Cells
    News - 27 Feb 2007
    Short pieces of RNA, known as small interfering RNA (siRNA), have the potential to become a new class of anticancer drugs if researchers can solve the problem of how to deliver these fragile molecules...
  • Perfluorocarbon Nanoparticles Track Living Cells
    News - 27 Feb 2007
    Stem cell therapy, primarily bone marrow transplantation, plays a key role in treating leukemia and other types of cancer. To better track the fate of stem cells injected into patients, researchers at...
