3d imaging

What Techniques are Used for 3D Imaging in Nanotechnology?

Several advanced techniques are employed for 3D imaging at the nanoscale, including:
Transmission Electron Microscopy (TEM): TEM can be used to create high-resolution 3D images by taking multiple 2D projections from different angles.
Scanning Electron Microscopy (SEM): SEM can provide detailed surface images, and when combined with techniques like Focused Ion Beam (FIB), it can produce 3D reconstructions.
Atomic Force Microscopy (AFM): AFM provides 3D surface topography information by scanning a probe over the material's surface.
X-ray Tomography: Often used for larger nanostructures, this technique reconstructs 3D images by compiling 2D X-ray images taken from different angles.
