Abstract
Disclosed is a moon grid for transmission electron microscopy tomography, including a mesh sheet for protecting an upper objects and a support film formed on the mesh sheet and having nanoparticles dispersed throughout, in which the nanoparticles dispersed throughout the support film are used as reference points in the reconstruction of two-dimensional transmission electron microscopy images into a three-dimensional image, thus omitting a process of attaching markers in the course of preparation of a sample and easily forming reference points even on a sample to which it is impossible to attach markers. A method of fabricating such a moon grid is also provided.
