  • Heat, Iron-Oxide Nanoparticles Improve Cancer Drug Delivery

    Pharmaceutical and engineering researchers at Oregon State University in Corvallis developed a technique with heated iron-oxide nanoparticles that in lab tests was shown to kill ovarian cancer cells with chemotherapy drugs. The team led by Oregon State pharmacy professor Oleh Taratula published its findings this month in an advance online paper in the International Journal of…

  • Super-Antioxidant Developed from Catalyst Nanoparticles

    Chemists and bioengineers at Rice University in Houston developed an antioxidant from an element used in catalytic converters that they found to be many times more powerful than antioxidants now on the market. The team from the labs of Vicki Colvin and Laura Segatori published their findings earlier this month in the journal ACS Nano…

  • Fortified Hydrogel Cartilage Regeneration Technique Devised

    Researchers at École polytechnique fédérale de Lausanne (EPFL) in Switzerland developed a method for delivering regenerative drugs at the right place and time to repair damaged cartilage tissue. The team from EPFL’s biomechanical orthopedics and polymers labs published advance results this week of their proof-of-concept tests in the journal Biomaterials (paid subscription required). Because cartilage has…

  • Programming Language Created for Synthetic DNA Chemistry

    Computer scientists and systems biologists at University of Washington, California Institute of Technology, and University of California in San Francisco are developing a coding language to enable the programming of synthetic DNA chemical interactions. A report from the team led by Washington computer scientist Georg Seelig appeared yesterday online in the journal Nature Nanotechnology (paid…

  • Small-Scale Ceramics Materials Engineered for Flexibility

    Materials scientists at Massachusetts Institute of Technology and Nanyang Technological University in Singapore created a new type of ceramics material with the ability to bend like metal, but retaining its strength. The team from the lab of MIT’s Christopher Schuh published its findings today in the journal Science (paid subscription required). The MIT-Singapore researchers developed…

  • Computer System Built with Carbon Nanotube Circuitry

    Engineers at Stanford University in California created a basic computer system of circuits made from carbon nanotubes rather than conventional semiconductors built on silicon. The team led by Stanford electrical engineering professors Subhasish Mitra and H.S. Philip Wong published its findings online today in the journal Nature (paid subscription required). As silicon semiconductors became smaller and packed more…

  • Biotech Start-Up Finds STD Treatment in Anti-Cancer Therapy

    Researchers with the biotechnology company TherapyX Inc. in Buffalo, New York found a potential treatment for the sexually transmitted disease (STD) gonorrhea in a therapy the company is developing for cancer. The team from TherapyX, a spin-off company of the University at Buffalo medical school, published its findings today online in the Journal of Infectious…

  • Graphene Photodetector Integrated with Semiconductor Chip

    Researchers at Vienna University of Technology and Johannes Kepler University in Linz, Austria built a detector and converter of optical signals with graphene into a traditional semiconductor chip, making it easier to integrate optics and electronics in a single device. The team led by Vienna’s Thomas Mueller published its findings online this week in the…

  • Nanodiamonds Improve Chemotherapy Targeting for Brain Tumors

    Researchers at University of California in Los Angeles, with colleagues from Northwestern University and Lurie Children’s Hospital of Chicago, developed a more precise delivery method for chemotherapy drugs using nanoscale diamonds to treat brain tumors. The team that included participants from the lab of UCLA biomedical engineering professor Dean Ho published their findings online in…

  • University of Houston Spins-Off Nanotech Coatings Company

    A physics professor at University of Houston in Texas started a company to develop and manufacture protective coatings for industrial and consumer goods based on his research in nanotechnology. C-Voltaics, started by Houston physicist Seamus Curran, was awarded last week the Young Technology Award at the Commercialization of Micro- and Nanosystems conference in The Netherlands, according…
