daily nanotechnology news
Researchers in Japan have developed a design concept for a device that allows imaging at scales previously impossible for optical instruments. Their advance is based on novel imaging techniques that allow optical imaging in the subwavelength regime, where the wavelength used is larger than the smallest features of the object being imaged.

RIKEN chemists have developed a catalyst that should allow carbon dioxide to be used as a versatile synthetic chemical.
The long-term vision of revolutionary bottom-up nanotechnology is based on two different concepts of molecular assembly technologies. One follows Nature's blueprint, which uses molecular recognition for self-assembly of nanoscale materials and structures; the other is man-made and uses instruments to assemble nanoscale building blocs into larger structures and devices. In contrast, the most common nanoscale fabrication techniques used today, for instance in the sub 100-nanometer semiconductor industry, are top-down approaches where fabrication technologies such as lithography or stamping are used. Here, you create ever smaller structures by starting with a block of material and remove the bits and pieces you don?t want until you get the shape and size you do want. While top-down techniques can be highly parallel (semiconductor industry) it is not feasible to control single molecules with them. Using a hybrid approach that combines the precision of an atomic force microscope with the selectivity of DNA interactions, researchers in Germany have successfully demonstrated a technique that fills the gap between top-down and bottom-up since it allows for the control of single molecules with the precision of atomic force microscopy and combines it with the selectivity of self-assembly.

In contrast to the often depicted model of a perfect hexagonal lattice cylinder shape of carbon nanotubes, these nanomaterials often become twisted, bent or otherwise deformed during their growth, processing, or characterization. Researchers have found that some of these defects can be associated with a rearrangement of atoms and bonds which in turn will impact on the band structure and therefore affects the electronic properties of the tube. Previous experimental Atomic Force Microscopy and Transmission Electron Microscopy studies of carbon nanotubes have clearly identified their susceptibility to collapse and theoretical predictions of the impact that these deformations have on the electronic properties have been formulated. Experiments at the University of Surrey in the UK are the first to show atomically resolved radially collapsed double-walled carbon nanotubes, bringing also clear evidence of changes in the fundamental electronic behavior of these systems in response to the deformation.

The study of individual live cells is a hugely important scientific task and essential to the field of molecular biology and biomedical research. Among the most significant technical challenges for performing successful live-cell imaging experiments is to maintain the cells in a healthy state and functioning normally on the microscope stage while being illuminated. Especially if scientists want to look into cellular processes that occur inside cells in their natural state and that cannot be observed by traditional cytological methods. Quantum dots (QDs), also called nanocrystals, hold increasing potential for in vitro and in vivo cellular imaging. For instance, we have previously reported about how researchers have used QDs for in vivo imaging of embryonic stem cells in mice, a novel technique that has opened up the possibility of using QDs for fast and accurate imaging applications in stem cell therapy. The usefulness of quantum dots comes from their peak emission frequency's extreme sensitivity to both the dot's size and composition. QDs have been touted as possible replacements for organic dyes in the imaging of biological systems, due to their excellent fluorescent properties, good chemical stability, broad excitation ranges and high photobleaching thresholds.
