The world’s most famous painting has now been created on the world’s smallest canvas. Researchers at the Georgia Institute of Technology have “painted” the Mona Lisa on a substrate surface approximately 30 microns in width – or one-third the width of a human hair.
Researchers from the National Institute of Standards and Technology (NIST) and the University of Maryland have shown how to make nanoscale measurements of critical properties of plasmonic nanomaterials.
JPK Instruments, a world-leading manufacturer of nanoanalytic instrumentation for research in life sciences and soft matter, reports on how researchers from the Université de Paris-Sud and CNRS Montpellier have used the new QI mode of AFM imaging to quantitatively characterize living bacteria without any immobilization.
Researchers of MESA+, the research institute for nanotechnology of the University of Twente, in cooperation with researchers of the University of Strasbourg and Eindhoven University of Technology, are the first to successfully create perfect one-dimensional molecular wires of which the electrical conductivity can almost entirely be suppressed by a weak magnetic field at room temperature.
The antibacterial effects of silver are well established. Now, researchers at Yonsei University in Seoul, Republic of Korea, have developed a technique to coat glass with a layer of silver ions that can prevent growth of pathogenic bacteria including Escherichia coli, Salmonella typhimurium and Campylobacter jejuni.
Every chemist’s dream – to snap an atomic-scale picture of a chemical before and after it reacts – has now come true, thanks to a new technique developed by chemists and physicists at the University of California, Berkeley.
When Felix Fischer of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) set out to develop nanostructures made of graphene using a new, controlled approach to chemical reactions, the first result was a surprise: spectacular images of individual carbon atoms and the bonds between them.
Professor Dr M. N. V. Ravi Kumar and Dr Dimitrios Lamprou, of the Strathclyde Institute of Pharmacy and Biomedical Sciences, believe an advanced form of atomic force microscopy, known as PeakForce QNM, could boost developments in the field of nanomedicines, the encapsulation of potent drugs in tiny particles measuring billionths of a meter in diameter. They described how this detailed imaging approach may also help scientists address growing concerns in the medical world around "nanotoxicology", the build-up of microscopic particles in people's tissues.
One of the basic principles of nanotechnology is that when you make things extremely small—one nanometer is about five atoms wide, 100,000 times smaller than the diameter of a human hair—they are going to become more perfect.
Friction is an omnipresent but often annoying physical phänomenon: It causes wear and energy loss in machines as well as in our joints. In search of low-friction components for ever smaller components, a team of physicists led by the professors Thorsten Hugel and Alexander Holleitner now discovered a previously unknown type of friction that they call “desorption stick.”
