  • Now in 3-D: Video of virus-sized particle trying to enter cell

    Tiny and swift, viruses are hard to capture on video. Now researchers at Princeton University have achieved an unprecedented look at a virus-like particle as it tries to break into and infect a cell. The technique they developed could help scientists learn more about how to deliver drugs via nanopar more

  • Smartphone 'microscope' can detect a single virus

    Aydogan Ozcan, a professor of electrical engineering and bioengineering at the UCLA Henry Samueli School of Engineering and Applied Science, and his team have created a portable smartphone attachment that can be used to perform sophisticated field testing to detect viruses and bacteria without the n more

  • Icy exposure creates armored polymer high tech foams

    Chemists and engineers at the University of Warwick have found that exposing particular mixtures of polymer particles and other materials to sudden freeze-drying can create a high-tech armored foam that could be used for a number of purposes, including a new range of low power room temperature gas s more

  • Good Reasons to Use ATR Libraries

    Transmission spectroscopy was the only method in general use until the early 1960s. The first applications of attenuated total reflection (ATR) or internal reflection spectroscopy were reported independently by Fahrenfort and Harrick. Especially macromolecular materials (rubbers, fibers, fabrics, coatings, laminates etc), which often failed to yield useful transmittance spectra, became accessible for infrared spectroscopic investigations by the ATR technique. Meanwhile, the ATR technique has been proven to be an extremely useful technique for material analysis and has become more widely used for all but gaseous samples. more

  • Optimization of Transfection Conditions for the Human HL-60 Promyelocytic Leukemic T-Cell Line Using FuGENE® HD Transfection Reagent

    Transfection is commonly performed to introduce many different types of molecules (plasmid DNA, RNA, siRNA, miRNA) into eukaryotic cell lines. Once inside, these molecules can be expressed in a transient or a stable fashion. In the case of transient transfection, molecules do not integrate into the host cell genome and are only expressed for approximately 24 hours - 96 hours post-transfection. 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
