Chemists have succeeded in making a layer of tiny protein coils attached to a surface, much like miniature bedsprings in a frame. This thin film made of stable and very pure helices can help researchers develop molecular electronics or solar cells, or to divine the biology of proteins.
Seeking to improve on nature, scientists used a spice-based compound as a starting point and developed synthetic molecules that, in lab settings, are able to kill cancer cells and stop the cells from spreading.
By combining custom-built spectrometers, novel probe designs and faster pulse sequences, a team led by Illinois chemistry professor Chad Rienstra has developed unique capabilities for probing protein chemistry and structure through the use of solid-state nuclear magnetic resonance spectroscopy.
University of Utah physicists successfully controlled an electrical current using the 'spin' within electrons - a step toward building an organic 'spin transistor': a plastic semiconductor switch for future ultrafast computers. The study also suggests it will be more difficult than thought to make highly efficient light-emitting diodes (LEDs) using organic materials.
An international team of researchers led by Monash University has used chemicals found in plants to replicate a key process in photosynthesis paving the way to a new approach that uses sunlight to split water into hydrogen and oxygen.
An AFOSR (Air Force Office of Scientific Research)-funded, Princeton-based professor has been researching a new approach to optical nanopatterning, the forming of nanometer scale patterns on a substrate. This technology will have an impact on a variety of current and future Air Force needs.
The Food and Drug Administration (FDA) is announcing a public meeting on September 8, 2008 to gather information that will assist the Agency in implementing the recommendations of the Nanotechnology Task Force Report.
The development of a transparent nanotechnology coating that causes water to bead up into drops and roll or bounce off a surface will help protect and sustain Air Force systems by preventing corrosion and reducing ice formation on optical elements and aircraft.
Statement of The Nanotechnology Panel of the American Chemistry Council (ACC), the NanoBusiness Alliance, and the Synthetic Organic Chemical Manufacturers Association?s (SOCMA) Nanotechnology SME Coalition Regarding the Status of EPA?s Nanoscale Materials Stewardship Program (NMSP).
Researchers at the Institute for NanoBioTechnology at Johns Hopkins University are discovering new properties and uses for a synthetic molecule that mimics collagen. When used with nanoparticles, this molecule, called collagen mimetic peptide (CMP) could produce detailed images of tumors, detect deadly buildup in arteries, deliver drugs, and improve blood supply to implanted tissues.
