Sentences with phrase «electron tomography»
Electron tomography is a technique used to create 3D images of tiny objects, like cells or nanoparticles, by using electrons instead of light. It allows scientists to see the detailed structure and arrangement of these objects at a very small scale. Full definition
The method, called individual - particle electron tomography (IPET), takes pictures of a target molecule from multiple viewing angles, and then combines these pictures to create one 3 - D, whole - molecule rendering, similar to how a medical computed tomography (CT) scan works.
