Confocal and Light Sheet Imaging

Optical imaging instrumentation can magnify tiny objects, zoom in on distant stars and reveal details that are invisible to the naked eye. But it notoriously suffers from an annoying problem: the…

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…

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…

FusionOptics in Neurosurgery and Ophthalmology – for a Larger 3D Area in Focus

Neurosurgeons and ophthalmologists deal with delicate structures, deep or narow cavities and tiny structures with vitally important functions. A clear, three-dimensional view on the surgical field is…

Brief Introduction to Freeze Fracture and Etching

Freeze fracture describes the technique of breaking a frozen specimen to reveal internal structures. Freeze etching is the sublimation of surface ice under vacuum to reveal details of the fractured…
