Nano-IR Photo-induced Force Microscopy (PiFM) – Robust & Stunning Nanoscale Chemical Imaging & Spectroscopy

Think of PiFM as supercharged nano-FTIR imaging with ~5 nm spatial resolution and superfast nanoscale IR spectroscopy (as fast as 0.1 second for full spectrum.) PiFM acquires both topography and chemical signature at the nanometer scale and demonstrates excellent sensitivity (monolayer), good correlation to bulk FTIR spectra, and universal applicability to a wide range of organic and inorganic materials. The images of PLA-ACM composite & spectra on the right were generated in <60 min. from start to finish. Click to see a video of the imaging session.

PiFM at Work

In addition to hyPIRTM (hyperspectral PiFM infrared images consisting of nano IR spectrum for each pixel), we are excited to share a hyperspectral s-SNOM image where s-SNOM signal as a function of wavelength is acquired at each pixel of this 128 x 128 image of hBN. Shown below are four s-SNOM images at four wavenumbers created from the hyperspectral image. Click to see a video of the full hyperspectral s-SNOM image.

Featured PiFM Applications

  • Vis-PiFM to Visualize Nanoscale Absorption in Perovskite Photovoltaic Film
    The chemical analysis of solar cell materials is an excellent application of Vis-PiFM. In a recent publication, our customers analyzed a ternary cation halide Cs0.05FA0.81MA0.14PbI2.55Br0.45 (CsFAMA)-based perovskite visual sensor that exhibits full-visible-spectra photovoltaic behavior and reconfigurable responsivity for adaptive image sensing and in-sensor machine vision.

  • Nanoscale Chemical Imaging of Soft Biological Tissues
    In one of our earlier blogs, we demonstrated PiFM’s capability in mapping the concentration of Li in LiFePO4. The results agreed qualitatively to the results obtained via X-ray absorption spectroscopy (XAS) microscopy on similar samples. In this blog, we highlight the capability of PiFM on […] Read more
