• AFM positioning: Shining light on a needle in a haystack

  The researchers characterize their new technique as a neat solution to the "needle in a haystack" problem of nanoscale microscopy, but it's more like the difference between finding the coffee table in a darkened room either by walking around until you fall over it, or using a flashlight. In a new pa 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

• The effects of hydrogen on growing carbon nanotubes

  Carbon nanotubes -- long, hollow cylinders of carbon billionths of a meter in diameter -- have many potential uses in nanotechnology, optics, electronics, and many other fields. The exact properties of nanotubes depend on their structure, and scientists as yet have little control over that structure more

• Automated Dynamic Light Scattering
  

  DLS analysis is a widely applied, non-invasive method for measuring the effective size of molecules in solution. This technique yields valuable information for the characterization of molecules and particles. It facilitates formerly laborious and time consuming measurements, e.g. screening for aggregates or determining optimal crystallization conditions for proteins. The Wyatt Plate Reader is the instrument of choice for any application where molecular size, stability and aggregation are of interest. It reads industry standard microplates with up to 1536 samples automatically and temperature-controlled, if desired. The applications of the technique are wide ranging and include many of the fastest growing areas of research - proteins, biomaterials, liposomes and micelles as well as the established uses for particle sizing and aggregation detection. Conscious of the numerous characterization challenges in the area of drug delivery systems and therapeutic antibodies more

• Nature's Ingenuity Shows the Way
  

  Up to 80 percent of our experience of our visual environment takes place via our visual perception. Without spatial vision, we would hardly be able to stay oriented. In recent decades, the neurosciences have gained many insights into the complex processes by which our brain's visual cortex and cerebral cortex do the fascinating job of processing the signals originating from the eyes into an image. A study carried out jointly by Leica Microsystems and the Institute of Neuroinformatics at the University of Zurich and Swiss Federal Institute of Technology showed how flexible and powerfull our brain joins visual signals to create an optimal spatial image. The results provided the basis for an innovation in stereomicroscopy which, in terms of resolution and focus depth, has broken through limits that were previously impossible to overcome. 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
