• 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

• Colon cancer screening technique shows continued promise in new study

  Recent clinical trials show that a new colon cancer screening technique created by Northwestern University researchers has a high enough sensitivity that it could potentially be as or more successful than a colonoscopy in screening for colon cancer. The technique uses optical technology, called low 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

• New Standard in Electrophysiology and Deep Tissue Imaging
  

  The function of nerve and muscle cells relies on ionic currents flowing through ion channels. These ion channels play a major role in cell physiology. One way to investigate ion channels is to use patch clamping. This method allows investigation of ion channels in detail and recording of the electric activity of different types of cells, mainly excitable cells like neurons, muscle fibres or beta cells of the pancreas. The patch clamping technique was developed by Erwin Neher and Bert Sakmann in the 1970s and 80s to study individual ion channels in living cells. In 1991 they received the Nobel Prize for Physiology and Medicine for their work. Today the patch clamping technique is one of the most important methods in the field of electrophysiology more

• Dynamic Light Scattering - an Important Tool for Protein Crystallography and Nanotechnology
  

  Dynamic Light Scattering (DLS) is an established technique in the field of protein crystallography. DLS is used to measure hydrodynamic sizes, polydispersities and aggregation effects of protein samples. These are important parameters for the crystallisation of proteins. DLS is also used in the nanotechnology research for the accurate and fast size measurement of nanoparticles made of different materials. more

• High‐precision characterization of individual E. coli cell morphology by scanning flow cytometry

  Abstract We demonstrate a flow‐cytometric method to measure length and diameter of single Escherichia coli cells with sub‐diffraction precision. The method is based on the original scanning flow cytometer that measures angle‐resolved light‐scattering patterns (LSPs) of individual particles. We m more
