  • New technique to sharpen microscope images

    The complexity of biology can befuddle even the most sophisticated light microscopes. Biological samples bend light in unpredictable ways, returning difficult-to-interpret information to the microscope and distorting the resulting image. New imaging technology developed at the Howard Hughes Medical more

  • Vibrational molecular pathology

    IR and Raman spectral imaging can distinguish between tissue types, disease types and stages, and even identify the primary tumors from spectral patterns observed in metastatic cells. Furthermore, these techniques can be used in the detection of circulating tumor cells. Spectral histopathology proce more

  • A new Concept in Microscopy: Self-reconstructing Laser Beams

    It’s a familiar situation for all car drivers. In the autumn, when the roads are foggy, visibility drops below 50 metres. The light of the car’s headlights are scattered by the drops of fog, meaning we can’t see objects further away because the light can’t reach them. This everyday example illustrat more

  • Measuring particle size using modern laser diffraction techniques

    Many different techniques have been devised for determining particle size distribution, but for a wide range of industries laser diffraction has become the preferred choice. Laser diffraction, alternatively referred to as Low Angle Laser Light Scattering (LALLS), can be used for the non-destructive analysis of wet or dry samples, with particles in the size range 0.02 to 2000 micron and has inherent advantages which make it preferable to other options for many different materials. 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

  • Do you see the complete picture?

    Gel permeation chromatography (GPC) or also named size exclusion chromatography (SEC) is the most often used method for determining the molecular weight of natural and synthetic macromolecules. One specific strength of this method lies in the fact that by the separation process the whole molecular weight distribution is obtained. The molecular weight distribution contains much larger information for the characterization of polymer samples compared to a single value. more
