Harvard researchers have developed a lightweight, portable nanofiber fabrication device that could one day be used to dress wounds on a battlefield or dress shoppers in customizable fabrics.
How do tumours grow? And how do bacteria transform harmless substances into medical agents? When biophysicists want to understand what is happening in living cells, they have to introduce fluorescent probes or other foreign molecules. There are several ways to overcome the cell wall without causing the cell permanent harm. Physicists at Bielefeld University have developed a particularly gentle method for this: nanoinjection.
Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
An international team of scientists has tailored special X-ray glasses to concentrate the beam of an X-ray laser stronger than ever before. The individually produced corrective lens eliminates the inevitable defects of an X-ray optics stack almost completely and concentrates three quarters of the X-ray beam to a spot with 250 nanometers diameter, closely approaching the theoretical limit. The team surrounding DESY lead scientist Christian Schroer presents its work in the journal Nature Communications.
Nanoclusters of magnesium oxide sandwiched between layers of graphene make a compound with unique electronic and optical properties, according to researchers at Rice University who built computer simulations of the material.
A new bioinspired process combines top-down and bottom-up assembly to turn silk protein into materials that are easily programmable at the nano-, micro- and macro-scales; ultralight; and robust. Structures made included a web of silk nano fibers able to sustain a load 4,000 times its own weight.
Sometimes, you have to go small to win big. That is the approach a multilab, interdisciplinary team took in using nanoparticles and a novel nanoconfinement system to develop a method to change hydrogen storage properties.
Successful results of a University of Liverpool-led trial that utilised nanotechnology to improve drug therapies for HIV patients has been presented at the Conference on Retroviruses and Opportunistic Infections (CROI) in Seattle, a leading annual conference of HIV research, clinical practice and progress.
Researchers from the Basque institutions CIC nanoGUNE, Ikerbasque and Cidetec, and the German Robert Koch-Institut report the development of hyperspectral infrared nanoimaging. It is based on Fourier transform infrared nanospectroscopy (nano-FTIR) and enables highly sensitive spectroscopic imaging of chemical composition with nanoscale spatial resolution.
A software tool and a systematic wet-lab procedure proven in practice are an advance in the design and construction of circuits made of DNA.
