Consumables for Laser Microdissection

There are many different types of consumables for laser microdissection (LMD) systems. They cover a wide range of applications from basic to highly specialized, enabling scientists to choose their own…

Universal PAINT – Dynamic Super-Resolution Microscopy

Super-resolution microscopy techniques have revolutionized biology for the last ten years. With their help cellular components can now be visualized at the size of a protein. Nevertheless, imaging…

Nanoscale or Microscale Structures Formed in Polymers Containing Nanotubes Greatly Enhance the Electrical Conductivity

The excellent mechanical and electrical properties of carbon nanotubes have led to them being exploited for the creation of a new class of high performance polymer composites. Due to important…

Immersion Freezing for Cryo-Transmission Electron Microscopy: Applications

A well established usage case for cryo-TEM is three-dimensional reconstruction of isolated macromolecules, virus particles, or filaments. On one hand, these approaches are based on averaging of…

Immersion Freezing for Cryo-Transmission Electron Microscopy: Fundamentals

The high vacuum required in a transmission electron microscope (TEM) greatly impairs the ability to study specimens naturally occurring in an aqueous phase: exposing "wet" specimens to a pressure…

Video Tutorials: Filling and Assembling of Different Carriers for High-Pressure Freezing

High pressure freezing (HPF) is a cryo-fixation method primarily for biological samples, but also for a variety of non-biological materials. It is a technique that yields optimal preservation in many…
