Question

Write the name of the technique used to know geometry of nanoparticles.

Answer 1

The geometry, size, and shape of nanoparticles are commonly determined using Transmission Electron Microscopy (TEM). This technique allows visualization of nanoparticles at the nanometer scale.

TEM provides detailed information about:

• Particle size and morphology
• Crystal structure and lattice fringes
• Particle aggregation and distribution

 

Other supporting techniques include:

• Scanning Electron Microscopy (SEM) – for surface morphology
• X-ray Diffraction (XRD) – for crystalline structure
• Atomic Force Microscopy (AFM) – for surface topography
