PiFM Applications
Visualization of Hermite Gaussian Focal Spot
The longitudinal focal field of a tightly focused light via high NA (1.45 NA) objective…
Visualize Nanoscale Absorption in Perovskite Photovoltaic Film using Vis-PiFM
The chemical analysis of solar cell materials is an excellent application of Vis-PiFM. In a…
Nanoscale Chemical Imaging of Soft Biological Tissues
In one of our earlier applications, we demonstrated PiFM’s capability in mapping the concentration of…
Bioplastic Nanocomposite – PLA, PiFM and Ecology
With global attention on the role that plastics play in our ecosystem, many researchers are investigating bioplastic alternatives such as polylactic acid.
Cross-section of a Semiconductor Trench
Vista-IR images a cross-section of a semiconductor trench via PiFM, highlighting two different materials based on their unique IR absorption bands.
Bacteriophage M13 and Plasmid DNA pUC1
Given the height of the bacteriophage M13 (3-4 nm), a single bacteriophage may have been imaged...
Meteorite – A Search for Organic Compounds
Molecular Vista's technology deconvolves the chemical composition of a meteorite...
Nanoscale Chemical Composition of Source Rock
Source rock or shale is a conglomeration of inorganic minerals – e.g, silicates and carbonates –…
Agreement Between PiFM and Conventional IR Spectra
PiFM spectra generally replicate conventional IR spectra recorded from bulk samples, shown in this example of polyethersulfone (PES).
Distinguishing Subtle Chemical Variants in Asphalt
The chemical mapping capability of PiFM is demonstrated in an asphalt sample containing multiple related…
Hexagonal Boron Nitride Optical Nano-dipole Antennae
PiFM captures ultra-confined resonances and local field enhancement in hexagonal boron nitride optical nano-dipole antennae.
Soap Formation in National Gallery Oil Painting
PiFM imaged the soap cross-section of a National Gallery sample to expose different chemical components found in a tiny piece of an oil painting. The formation of soap aggregates is of growing concern to art conservation and restoration, especially in traditional 15th to 20th century oil paintings.
