Scientists in the US have used the DNA from fish waste to make optical components. The team, led by James Grote of the US Air Force Research Laboratory, says that the material could be used to make optical waveguides, modulators and light-emitting diodes. They also claim that fish DNA, which is abundant and environmentally friendly, could outperform other polymer-based devices.
Penn State University researchers have developed a prototype sonic gas analyser that automatically and continuously tracks the concentration of a gas in an air/gas mixture based on changes in pitch.
Physicists in Switzerland and Germany have made a new type of optical microscope that can produce images without capturing light from the sample. The new device relies on measuring changes in the properties of a gold nanoparticle placed next to the sample. The nanoantenna could have application in sensing devices (Phys Rev Lett 95 200801).
Resonance Health's non-invasive liver diagnostic technology uses magnetic resonance imaging (MRI) technology to provide a scan of the liver which is subsequently analysed to quantify iron loading using FerriScan's proprietary software. It is a novel technology easily applied to anyone with an MRI machine.
The Phenomenex Onyx C18 Semi-Prep 100 x 10 mm is the latest addition to the portfolio of monolithic silica HPLC columns. This format allows for flow rates from 5 to 35 mL/min with loading capacities typically between 10 and 20 mg. Onyx Semi-Prep is suitable for high-throughput purifications where impure samples and abusive ballistic gradients are encountered, such as in combinatorial library purifications. Also, due to the physics of the monolith, the DMSO solvent slug is well mixed, improving purification results. In addition to high-throughput purification advantages Onyx has very low backpressures and good flow characteristics, which allows for injection of very dirty and/or viscous sample.
A Stanford University research team has designed the first microscope sensitive enough to track the real-time motion of a single protein down to the level of its individual atoms
Varian has debuted its first shielded vertical high-resolution superconducting magnets designed to reduce stray magnetic fields by up to fivefold (in volume), allowing researchers to save space in pharmaceutical and academic laboratories and making nuclear magnetic resonance (NMR) more accessible for routine applications. The 500 and 600 MHz premium shielded magnets are integrated with the company's Varian NMR System and are compatible with its suite of cold and room temperature NMR probes.
Researchers at Rice University, the Baylor College of Medicine, the University of Houston and the Ecole Polytechnique Federale de Lausanne in Switzerland have created what they claim is a new class of magnetic resonance imaging contrast agents that are at least 40 times more effective than the best in clinical use.
New Objective has released an LCMS source: the PicoView 500 series. Designed to fit the Finnigan series of ion trap mass spectrometers and optimised for low flow rate operation the sources provide optimum sensitivity for peptide and protein analysis.
Five years ago, x-ray crystallography made it possible for the first time to study ribosomes in cells, where the synthesis of proteins takes place. But it hasn't been understood just how amino acids are joined together to form proteins. Now researchers at Uppsala University have discovered the only possible mechanism and have used it to explain a number of biochemical experiments.
