nanoparticle size distributions

How is Size Distribution Measured?

Several techniques are employed to measure the size distribution of nanoparticles:
Dynamic Light Scattering (DLS): This technique measures the fluctuations in the intensity of scattered light to determine particle size distribution.
Transmission Electron Microscopy (TEM): Provides high-resolution images that can be used to measure the size of individual nanoparticles.
Scanning Electron Microscopy (SEM): Similar to TEM but uses surface scanning to provide size information.
Atomic Force Microscopy (AFM): Provides topographical maps that can be used to measure nanoparticle dimensions.
Nanoparticle Tracking Analysis (NTA): Tracks the movement of individual nanoparticles to determine their size distribution.
