EM RESOLUTIONS-Holey Carbon Film on Copper/ Gold / Nickel
Holed carbon films have many uses in microscopy, but for some applications the mesh size of standard TEM grids is too large to support the sample.
Continuous carbon films can also be a problem because the film can inelastically scatter electrons and cause background noise.
Therefore, porous carbon membranes are a suitable alternative.
Porous carbon films have pores of different sizes.
In addition to providing support, the enhanced image contrast of the pore area compared to the membrane area is also beneficial. Typical applications include biology, materials science, and cryo-TEM.
