Growth of Nanoholes Visible for the First Time Thanks to Helium Scattering

Scientists were able to observe and document the growth of hexagonal boron nitride for the first time

28-Oct-2022 - Atomically thin 2D materials for applications in microelectronics or nanotechnology are grown by breaking down gas on a hot metal surface. Due to the high temperatures and rapid transformation of the gas, it is extremely difficult to observe this process. Researchers from TU Graz have now joined ...

A "nano-robot" built entirely from DNA to explore cell processes

02-Aug-2022 - Constructing a tiny robot from DNA and using it to study cell processes invisible to the naked eye... You would be forgiven for thinking it is science fiction, but it is in fact the subject of serious research by scientists from Inserm, CNRS and Université de Montpellier at the Structural Biology ...

First electric nanomotor made from DNA material

Synthetic rotary motors at the nanoscale perform mechanical work

27-Jul-2022 - A research team led by the Technical University of Munich (TUM) has succeeded for the first time in producing a molecular electric motor using the DNA origami method. The tiny machine made of genetic material self-assembles and converts electrical energy into kinetic energy. The new nanomotors ...

Nanotechnology enables visualization of RNA structures at near-atomic resolution

Combination of nucleic acid nanotechnology and cryo-EM gives unprecedented insights into the structures of large and small RNAs

04-May-2022 - We live in a world made and run by RNA, the equally important sibling of the genetic molecule DNA. In fact, evolutionary biologists hypothesize that RNA existed and self-replicated even before the appearance of DNA and the proteins encoded by it. Fast forward to modern day humans: science has ...

Complete filling of batches of nanopipettes

10-Jan-2020 - Nanopipettes, in which a nanoscale channel is filled with a solution, are used in all kinds of nanotechnology applications, including scanning-probe microscopy. Bringing a solution into a nanopipette with a pore diameter below 10 nanometer is challenging, however, since capillary forces prevent ...

Researchers examine 'living' nanomaterials for first time

New technology gives insight into how nanomaterials form and grow

01-Jul-2019 - A new form of electron microscopy allows researchers to examine nanoscale tubular materials while they are "alive" and forming liquids -- a first in the field. Developed by a multidisciplinary team at Northwestern University and the University of Tennessee, the new technique, called variable ...

Novel quantum dots enhance cell imaging

31-Oct-2018 - A team of researchers from the University of Illinois at Urbana-Champaign and Mayo Clinic have engineered a new type of molecular probe that can measure and count RNA in cells and tissue without organic dyes. The probe is based on the conventional fluorescence in situ hybridization (FISH) ...

A nanotech sensor that turns molecular fingerprints into bar codes

11-Jun-2018 - Infrared spectroscopy is the benchmark method for detecting and analyzing organic compounds. But it requires complicated procedures and large, expensive instruments, making device miniaturization challenging and hindering its use for some industrial and medical applications and for data ...

A faster and more efficient way to process information

15-May-2018 - University of Waterloo chemists have found a much faster and more efficient way to store and process information by expanding the limitations of how the flow of electricity can be used and managed. In a recently released study, the chemists discovered that light can induce magnetization in ...

Revolutionizing cancer research with diamonds

12-Mar-2018 - Magnetic resonance imaging (MRI) is being revolutionized: With the nanodiamond the tumor tissue can be detected sooner and distinguished better from the healthy surrounding tissue. Aiming at an improvement of the MRI procedure in the joint project »DiaPol« Fraunhofer IAF cooperates with the ...
