Researchers report the design and fabrication of the smallest optical device, capable of detecting and sensing individual biomolecules at concentrations that are similar to those found in the cellular context.
Nanotechnologies require a detailed knowledge of the molecular state. For instance, it is useful to know when and how a generic polymer, a long chain of polymers (chain of beads), knots. The study of molecular entanglement is an important field of study as the presence of knots affects its physical properties, for instance the resistence to traction.
Lone people standing in a ballroom don't tend to move a lot. It's only when they find a suitable dance partner that rapid motion sets in. Atoms on iron-oxide surfaces behave in a similar way: Only with the right molecular partner do they dance across the surface. Scientists have now filmed the atoms, proving that carbon monoxide is the partner responsible for the quick motion.
Scientists have been able to measure weak forces with sensitivity 50 times higher than what has been achieved to date. This significant improvement represents a turning point in measuring very weak forces and opens the door for magnetic resonance imaging at the molecular scale.
This report on Regional, State, and Local Initiatives in Nanotechnology is the result of a workshop convened 1-2 May 2012 in Portland, Oregon, by the Nanoscale Science, Engineering, and Technology (NSET) Subcommittee of the National Science and Technology Council.
An 'artificial cricket hair' used as a sensitive flow sensor has difficulty detecting weak, low-frequency signals - they tend to be drowned out by noise. But now, a bit of clever tinkering with the flexibility of the tiny hair's supports has made it possible to boost the signal-to-noise ratio by a factor of 25.
CEA-Leti will present recent advances and a preview of future developments in micro- and nanotechnologies, followed by workshops on key technical fields, during Leti Innovation Days, June 25-28, on the MINATEC campus.
Researchers have synthesized a novel framework structure consisting of boron and silicon, which could be suitable as an electrode material. Similar to the carbon atoms in diamond, the boron and silicon atoms in the novel lithium borosilicide are interconnected tetrahedrally. But unlike the diamond they form additional channels.
This strategic document provides a set of key recommendations for the European Commission and the EU Member States to create a favourable ecosystem for the successful deployment of Nanomedicine in Europe. It lays thereby the groundwork to manage the efficient translation of nanotechnology from a Key Enabling Technology (KET) into new and innovative medical products.
Researchers have reported the first observation of the 'spin Hall effect' in a Bose-Einstein condensate, a cloud of ultracold atoms acting as a single quantum object. As one consequence, they made the atoms, which spin like a child's top, skew to one side or the other, by an amount dependent on the spin direction.
Researchers at the University of Illinois at Urbana-Champaign have developed a new flow-based method for manipulating and confining single particles in free solution, a process that will help address current challenges faced by nanoscientists and engineers.
