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…

Glycerol Spraying/Platinum Low Angle Rotary Shadowing of DNA with the Leica EM ACE600 e-beam

Glycerol spraying/low angle rotary shadowing (Aebi and Baschong, 2006) is a preparation technique used in biology to visualize structures yielding insufficent contrast with other techniques, due to…

Brief Introduction to Coating Technology for Electron Microscopy

Coating of samples is required in the field of electron microscopy to enable or improve the imaging of samples. Creating a conductive layer of metal on the sample inhibits charging, reduces thermal…

Carbon Thickness Evaluation in Electron Microscopy

The coating layers applied and used for electron microscopy imaging are commonly controlled and measured by quartz crystals. These crystals oscillate with a certain frequency (around 6 megahertz when…
