  • A well-matched couple

    Photoacoustic (PA) imaging is a method to visualize structures with optical contrast in biological tissue. Despite the strong optical scattering in tissue, high resolution images in the visible and near infrared spectral range can be obtained. The method is based on sound waves which are generated i more

  • Breaking the final barrier: Room-temperature electrically powered nanolasers

    A breakthrough in nanolaser technology has been made by Arizona State University researchers. Electrically powered nano-scale lasers have been able to operate effectively only in cold temperatures. Researchers in the field have been striving to enable them to perform reliably at room temperature, a more

  • A non-invasive intracellular 'thermometer' with fluorescent proteins has been created

    A team from the Institute of Photonic Sciences (ICFO) has developed a technique to measure internal cell temperatures without altering their metabolism. This finding could be useful when distinguishing healthy cells from cancerous ones, as well as learning more about cellular processes.Temperature c more

  • LightCycler® 480 System: High-throughput Gene Expression and Genotyping Analysis - A Performance Study

    The LightCycler® 480 System is a novel platform for rapid gene expression and melting curve-based genotyping for medium- and high-throughput. In order to assess the performance and ease-of-use of the complete LightCycler® 480 System (instrument, software, and reagents) in an academic laboratory setting we scheduled a high-throughput project including gene expression (39 targets in 88 samples = 3,400 expression values) as well as genotyping applications (3,808 genotypes; 14 SNPs in 288 samples). The project, involving five technicians and two graduate students, was accomplished within 15 working days. more

  • Experimental Workflow for Fast and Accurate Genotyping of Scrapie-resistant/sensitive Sheep

    Several scientific studies support the claim that natural scrapie is associated with polymorphisms at three codons within the sheep prion protein (PrP) gene. Genotyping of these codons (codon 136 [alanine, valine], 154 [arginine, histidine], and 171 [glutamine, arginine, histidine]) might enable breeding of sheep flocks with high resistance to scrapie. Fast and reliable high-throughput genotyping of sheep is a major issue, since scrapie is a serious problem in several European countries. To address this, an experimental procedure for DNA preparation and PCR-based detection of codon 136, 154, and 171 polymorphisms was established. more

  • The Determination of Hazardous Substances According to RoHS and WEEE Directives

    1st July 2006 is an important deadline for the electro- and electronics industries. This date bans hazardous substances like lead, cadmium, mercury, hexavalent chromium and polybrominated biphenyls and diphenyl ethers from electro- and electronic equipment. This restriction, even though in discussion since 1991, has become more and more important from year to year because of tons of electronic waste releasing toxic substances which are accumulated in the environment, the food chain and all human beings. In order to enforce the substances ban and the limitation or substitution of hazardous components, elemental analysis is obviously the most important control measure for monitoring limiting values. This requires precise analytical systems such as X-ray fluorescence, ICP- and atomic absorption spectrometers. These instruments are able to detect trace concentrations of hazardous compounds - for example cadmium, using an atomic absorption spectrometer in the flame atomization mode up to 0.1 mg/L, or using the di more
