Researchers at the nanotechnology research centre imec (Leuven, Belgium) have demonstrated biosensors based on novel nanostructure geometries that increase the sensitivity and allow to detect extremely low concentrations of specific disease markers.
A sensitive measuring device must not be dropped - because this usually destroys the precision of the instrument. A team of researchers including scientists from the Max Planck Institute of Quantum Optics has done exactly this, however. And the researchers want to use this experience to make the measuring instrument even more sensitive.
What could be better than diamond when it comes to a superhard material for electronics under extreme thermal and pressure conditions? Quite possibly BC5, a diamond-like material with an extremely high boron content that offers exceptional hardness and resistance to fracture, but unlike diamond, it is a superconductor rather than an insulator.
Mayo Clinic and the University of Illinois at Urbana-Champaign are announcing a strategic alliance designed to promote a broad spectrum of collaborative research, development of new technologies and clinical tools, and design and implementation of novel education programs.
By emulating nature's design principles, a team of researchers has created nanodevices made of DNA that self-assemble and can be programmed to move and change shape on demand. In contrast to existing nanotechnologies, these programmable nanodevices are highly suitable for medical applications because DNA is both biocompatible and biodegradable.
Thailand's National Nanotechnology Center (NANOTEC), National Institute of Metrology (NIMT) and Ministry of Science and Technology have announced that they would form the country's first research collaboration to build Thailand's capabilities in providing quality infrastructure in areas related to nano-scale measurement, calibration, and nanometrology.
The Freiburg Materials Research Centre (FMF), which is part of the University of Freiburg, recently celebrated its 20th anniversary in the Freiburg Concert Hall. As a central institution of the University of Freiburg, the FMF has been focusing on interdisciplinary basic research and contract research in the field of new materials and materials-related technologies since 1990.
Imagine a pen-sized device to check your skin for melanoma. You skim the surface of your skin, and, if necessary, the pen advises you to see your physician to have a closer look at a certain spot. Such a pen would scan your skin, and detect if skin cancer is developing, even in an early stage. It would distinguish between healthy and suspicious spots, even if you can see no difference.
Imec has fabricated electrical sources of surface plasmons, based on integrating light emitting diodes with metal-insulator-metal (MIM) waveguides. These sources, together with earlier work demonstrating plasmon detectors, are a prerequisite for making an interface between electronics and plasmonic circuits. This will lead the way to fully integrated plasmonic biosensing.
GeSn materials show promise, for example as embedded source/drain stressors for Ge channels in future pMOS devices. Imec has started a collaboration to assess the possible applications of GeSn materials, and to see how these applications could be implemented. First results show, among others, that GeSn (with 2-8% Sn) materials are compatible with conventional source/drain engineering processes.
An ethanol vapor sensor is fabricated using a ZnO nanoparticle film as a coating on a silicon-on-insulator (SOI) microring resonator of 5 micrometer in radius. The sensor can detect ethanol vapor concentrations as low as 100ppm. This achievement successfully demonstrates the potential of SOI technology for the development of sensitive, compact, low-power and inexpensive optical gas sensing devices.
Imec realized a vertical Flash transistor with Si plug diameters down to 20nm. The associated vertical Flash platform paves the way to scale Flash memory to the next nodes. The vertical device concept features enhanced performance at lower voltages as well as reduced cost.
