  • 'Nanocamera' takes pictures at distances smaller than light's own wavelength

    Researchers at the University of Illinois at Urbana-Champaign have demonstrated that an array of novel gold, pillar-bowtie nanoantennas (pBNAs) can be used like traditional photographic film to record light for distances that are much smaller than the wavelength of light (for example, distances less more

  • No compromises: Short, flexible, reusable AFM probe

    JILA researchers have engineered a short, flexible, reusable probe for the atomic force microscope (AFM) that enables state-of-the-art precision and stability in picoscale force measurements. Shorter, softer and more agile than standard and recently enhanced AFM probes, the JILA tips will benefit na more

  • Weighing particles at the attogram scale

    MIT engineers have devised a way to measure the mass of particles with a resolution better than an attogram — one millionth of a trillionth of a gram. Weighing these tiny particles, including both synthetic nanoparticles and biological components of cells, could help researchers better understand th more

  • Quantitative Detection of Legionella pneumophila in Water Samples: Assay Transfer to the LightCycler® 480 Real-Time PCR System

    An assay to detect and quantify Legionella spp. in water samples was successfully transferred from a capillary-based LightCycler® Instrument to the novel multiwell plate-based LightCycler® 480 System. A previously described protocol was easily adapted by modifying the fluorescent label of the detection probe to match the filter set of the LightCycler® 480 Instrument. While reproducibility and analytical sensitivity of the assay were found to be comparable on both systems, the novel plate-based instrument allowed for higher sample throughput and reduced assay time per sample. more

  • Field-Flow Fractionation - The Universal Separation Principle for Particle and Macromolecule Characterization

    High molecular weight polymers, bio molecules or particles in a range of a few nanometers up to several microns are more and more important in science and technology. Many applications are based on the specific properties of these materials. For this reason, an exact knowledge of the molar mass or particle sizes distribution is essential for later application as well as for optimization of the production processes or quality control. In addition the knowledge about the chain structure of macromolecules or biopolymers as well as about the shape of particles is often necessary. For this reason those samples, which often can be very complex systems, have to be separated according to parameters such as e.g. hydrodynamic volume or molecular weight. After the separation process the resulting narrow dispersed fractions are detected with different techniques. more

  • LOOXSTER® concentrates bacterial DNA

    Detection of the bacterial content of a specific sample, irrelevant from its source, is not as straightforward as it seems. In clinical microbiology laboratories, the gold standard method for the detection of pathogens in patients suspected of systemic infections is the blood culture. However, this technique is known to have many drawbacks especially with regard to patient's antibiotics treatment, low abundance and non-cultivable organisms. Moreover, it takes usually 3 to 5 days to obtain a result from blood culture which is too late to initiate proper antibiotic therapy. Amplification-based methods such as PCR allow results in a more rapid fashion. However, their sensitivity, to date, are no better, and sometimes worse, than culture-based methods. more
