Holey Carbon Films With 2 nm Continuous Carbon On Top
Quantifoil® is a holey carbon film with a special geometry and a thickness of about 12 nm, that is applied on a standard copper electron microscopy grid and provides an ideal support for biological samples in cryo-EM techniques[1-8]. Higher mesh numbers (300) indicate closely spaced bars and provide higher stability, whereas lower numbers (200) provide larger free faces. The Quantifoil® carbon film has circular holes of defined size and interspace, e.g. R 2/1 (pictured) has holes of 2 µm diameter with an interspace of 1 µm in both dimensions. The C2 versions on this page provide an additional 2 nm continuous carbon layer on top.
