AFM microscope, model MultiView 1000 and 2000TM, from Nanonics Imaging Limited, Israel

Features:  The Nanonics MultiView 2000™
AFM Microscope is the only microscope which allows for both tip and sample scanning. Multiview 1000™ is capable of scanning in a liquid environment as well as solid samples It can be integrated with Raman/FTIR Raman- AFM for taking Raman

spectra simultaneously with AFM scan, Tip enhanced Raman spectroscopy for enhancing Raman signals.
Performance: Lateral and axial scan range upto 70 µm for very rough samples. Olympus microscope with 10X and 50X objectives for higher resolution. Operates in non- contact mode. Capable of tip enhanced Raman spectroscopy.

Sample Preparation: Preferable sample size 1 cm X 1 cm.

Properly adhered to substrate (glass/mica/silicon).

Maximum scan area 70 µm X 70 µm can be done. Minimum 2 µm X 2 µm.

Tip size is 10 nm, so particles cannot be resolved below this dimension.

For fabrics and yarns as it is samples can be done.

For nanoparticles/ Nanodispersions (if nanoparticle disperse in appropriate solvent)

1 wt% gelatine solution should be prepared and applied on the substrate (can be glass coverslip/mica sheet or any other smooth substrate with preferable dimension of 1 cm X 1 cm) as very thin film

Dry at room temp for 2-3 hr

Apply nanoparticle dispersion on it and dry again.


  • Dispersion should not be in form of aggregates.
  • Diluted solutions are preferred for good dispersion and individual particles.
  • Sample should be properly dried. Wet samples can not be done
  • Sample should be adhered properly to substrate and should not stick to tip during scan.
  • Liquid samples can not be done as it is.

SEM Image of same sample is must before AFM

Applications: AFM allow surface morphology characterization of highly irregular surfaces using intermittent modes with information on height, amplitude, error and phase signals. Used for variety of samples such as nanofibers, fabrics, thin films etc.
