  • Researchers synthesize gold nanoparticles capable of attacking cancer cells
    24 hours

    A team of NYU Abu Dhabi (NYUAD) researchers have developed a new, one-pot synthetic approach to obtain water-stable and "ready to use" gold nanoparticles that can be heated with a simple green laser, improving the gold nanoparticles' ability to penetrate and destroy malignant cells through hyperthermia and simultaneously releasing chemotherapeutic drugs. The unique design of these nanoparticles reduces the side effects of the drugs, potentially improving patients' quality of life.

  • Researchers create unique DNA biosensor for early stage disease detection
    1 day

    Disease detection at an early stage is one of the biggest challenges biochemists and materials scientists are trying to meet by combining their expertise at Missouri S&T. The researchers used nanotechnology in biomedical diagnostics—a process called nanodiagnostics—to create a new, ultrasensitive DNA biosensor. The new sensor could potentially detect DNA-based biomarkers for early diagnosis of cancer and genetic disorders, as well as monitor patient responses to therapies.

  • Engineer uses metal-oxide nanomaterials deposited on cloth to wipe out microbes
    1 day

    In an effort to make highly sensitive sensors to measure sugar and other vital signs of human health, Iowa State University's Sonal Padalkar figured out how to deposit nanomaterials on cloth and paper.

  • Personalized microrobots swim through biological barriers, deliver drugs to cells
    2 days

    Tiny biohybrid robots on the micrometer scale can swim through the body and deliver drugs to tumors or provide other cargo-carrying functions. The natural environmental sensing tendencies of bacteria mean they can navigate toward certain chemicals or be remotely controlled using magnetic or sound signals.

  • Atomic force microscopy reveals high heterogeneity in bacterial membrane vesicles
    2 days

    One aspect of bacterial activity is the production of so-called extracellular membrane vesicles (MVs): biological 'packages' wrapped in a lipid-bilayer membrane, carrying for example genetic material. Apart from having specific biological functions, MVs are increasingly used in nanobiotechnological applications, including drug delivery and enzyme transport. In order to better understand the processes involving MVs, a full apprehension of their physical properties is essential. In particular, […]

  • New method to monitor Alzheimer's proteins
    2 days

    Physicists at the Center for Integrated Nanostructure Physics (CINAP), within the Institute for Basic Science (IBS, South Korea), have reported a new method to identify the aggregation state of amyloid beta (Aβ) proteins in solution. Published in ACS Nano, this finding could represent a step forward in the early diagnosis of Alzheimer's disease.

  • Researchers use nanotechnology to develop new treatment for endometriosis
    3 days

    Scientists have developed a precise, nanotechnology-based treatment to alleviate the pain and fertility problems associated with endometriosis, a common gynecological condition in women of childbearing age.

  • Phage capsid against influenza: Perfectly fitting inhibitor prevents viral infection
    1 week

    A new approach brings the hope of new therapeutic options for suppressing seasonal influenza and avian flu. On the basis of an empty and therefore non-infectious shell of a phage virus, researchers from Berlin have developed a chemically modified phage capsid that stifles influenza viruses.

  • Heart attack on a chip: Scientists model conditions of ischemia on a microfluidic device
    1 week

    Researchers led by biomedical engineers at Tufts University invented a microfluidic chip containing cardiac cells that is capable of mimicking hypoxic conditions following a heart attack—specifically when an artery is blocked in the heart and then unblocked after treatment. The chip contains multiplexed arrays of electronic sensors placed outside and inside the cells that can detect the rise and fall of voltage across individual cell membranes, as well as voltage waves moving across the […]

  • 3-D printed sensors could make breath tests for diabetes possible
    2 weeks

    The production of highly sensitive sensors is a complex process: It requires many steps and the almost dust-free environment of special cleanrooms. A research team from Materials Science at Kiel University (CAU) and from Biomedical Engineering at the Technical University of Moldova has now developed a procedure to produce extremely sensitive and energy-efficient sensors using 3-D printing. The simple and cost-effective production method is also suitable for industrial production, the team […]
