Question
Discuss the various analytical tools used for characterization of nanoparticles.
✓
Answer
The analytical tools used for characterization of nanoparticles are
- U.V visible spectroscopy – It gives the preliminary confirmation of formation of nanoparticles.
- X-ray Diffraction (XRD) – The information given by this tool is about particle size, crystal structure and geometry.
- Scanning electron microscopy (SEM) : This is used to study the structure of surface of material that is the morphology of the material.
- Transmission electron microscopy (TEM) gives information about the particles size.
- (FTIR) Fourier transform infrared spectroscopy gives information about absorption of functional groups and binding nature of the nanomaterial.
