Photo-induced Force Microscopy (PiFM): Augmenting Surface Analysis with AFM Chemical Mapping

Photo-induced Force Microscopy (PiFM) is a new-age analytical technique that revolutionizes Atomic Force Microscopy (AFM) with chemical mapping capabilities. This groundbreaking technology is orders of magnitude more sensitive and precise than FTIR yet maintains comparable spatial resolutions to other advanced AFM modes.

These combined features make PiFM a powerful complement to other surface analytical techniques, giving researchers new lenses to illuminate the chemistry and performance of interface materials.

Join us on June 29, 2023, at 11 AM PDT to discover how PiFM can augment the data and results from common surface techniques, unlocking key insights for industrial and scientific research.

This Webinar Will Answer:

  1. How does PiFM work?
  2. What are the key advantages and features of this technique?
  3. How does PiFM compare to other surface analysis techniques?
  4. How is PiFM used in industry to augment insight from existing surface analysis methods?

The Next Generation of IR-Spectroscopy Analysis: Going Nano

Individual spectra are similar to those generated in Fourier-transformed Infrared (FTIR) spectroscopy, except PiFM has a spectral resolution 109 times more precise. This enables PiFM to isolate and distinguish chemical signatures at an even more exacting scale than the spectral fingerprinting of classical FTIR.

Though that’s a staggering performance boost, the real game-changer of PiFM is its facility for nano-scale chemical mapping. With a spatial resolution better than 5 nanometers, PiFM can illuminate material phase distributions, chemical defects, and contaminants within nanoscale areas. What’s more, it can be calibrated to probe the chemistry of a sample at varying depths, mapping the makeup of the sample with mono-layer molecular sensitivity.

PiFM technology enables experts to investigate the chemistry of smaller volumes than ever, providing a “unique window in the study of complex material systems.” [1]

Covalent is proud to partner with the creators of PiFM at Molecular Vista to introduce you to the capabilities and applications of this technique.
