  • Controlled rupturing of thin films can make low-cost nanopatterned arrays for solar cells and biomolecular detection ۱۳۹۶/۴/۷

    The phenomenon of 'dewetting'—usually considered a nuisance as it causes solids to bead up into islands, much like raindrops on glass—has been harnessed for a useful application. An A*STAR-led team has clarified how dewetting can assemble arrays of 3-D nanostructures for applications including single molecule sensing.

  • A levitated nanosphere as an ultra-sensitive sensor ۱۳۹۶/۴/۷

    Sensitive sensors must be isolated from their environment as much as possible to avoid disturbances. Scientists at ETH Zurich have now demonstrated how to remove from and add elementary charges to a nanosphere that can be used for measuring extremely weak forces.

  • Researchers measure light fields in 3-D ۱۳۹۶/۴/۵

    Researchers from TU Graz and the University of Graz present the new method of 3-D-plasmon tomography in Nature Communications.

  • Switchable DNA mini-machines store information ۱۳۹۶/۴/۱

    Biomedical engineers have built simple machines out of DNA, consisting of arrays whose units switch reversibly between two different shapes.

  • Holey pattern boosts coherence of nanomechanical membrane vibrations ۱۳۹۶/۴/۱

    Researchers at the Niels Bohr Institute have introduced a new type of nanomechanical resonator, in which a pattern of holes localizes vibrations to a small region in a 30 nm thick membrane. The pattern dramatically suppresses coupling to random fluctuations in the environment, boosting the vibrations' coherence. The researchers' quantitative understanding and numerical models provide a versatile blueprint for ultracoherent nanomechanical devices. Among others, this enables a new generation of nanomechanical sensors to probe quantum limits of mechanical measurements, and more sensitive force microscopy. The results are published in the prestigious scientific journal, Nature Nanotechnology.

  • Injectable plant-based nanoparticles delay tumor progression ۱۳۹۶/۴/۷

    Researchers from Case Western Reserve University School of Medicine in collaboration with researchers from Dartmouth Geisel School of Medicine and RWTH Aachen University (Germany) have adapted virus particles—that normally infect potatoes—to serve as cancer drug delivery devices for mice. But in a recent article published in Nano Letters, the team showed injecting the virus particles alongside chemotherapy drugs, instead of packing the drugs inside, may provide an even more potent benefit.

  • Graphene and terahertz waves could lead the way to future communication ۱۳۹۶/۴/۷

    By utilizing terahertz waves in electronics, future data traffic can get a big boost forward. So far, the terahertz (THz) frequency has not been optimally applied to data transmission, but by using graphene, researchers at Chalmers University of Technology have come one step closer to a possible paradigm shift for the electronic industry.

  • Hacking the human brain—lab-made synapses for artificial intelligence ۱۳۹۶/۴/۷

    One of the greatest challenges facing artificial intelligence development is understanding the human brain and figuring out how to mimic it. Now, one group reports in ACS Nano that they have developed an artificial synapse capable of simulating a fundamental function of our nervous system—the release of inhibitory and stimulatory signals from the same "pre-synaptic" terminal.
