Peak force infrared (PFIR) microscopy is an emerging atomic force microscopy (AFM)-based
infrared microscopy that bypasses Abbe's diffraction limit on spatial resolution. The PFIR …

For decades, infrared (IR) spectroscopy has advanced on two distinct frontiers: enhancing
spatial resolution and broadening spectroscopic information. Although atomic force …

Atomic force microscopy (AFM)-based nanoscale infrared (nano-IR) techniques have found
extensive application in the fields of chemistry, physics, and materials science, enabling the …

The mechanical detection of photothermal expansion from infrared (IR) absorption with an
atomic force microscope (AFM) bypasses Abbe's diffraction limit, forming the chemical …

Photothermal spectroscopy has proven to be an incisive analytical tool, with several
offshoots and applications. It is desirable to extend this technique to interfacial spectroscopy …

While a standard microscope provides detailed images of a sample's shape, an infrared (IR)
microscope visualizes the distribution of chemicals within the sample. This label-free method …

Nanometer-scale chemical analysis requires microscopy that delivers high spatial resolution
and chemical sensitivity. Atomic force microscope-infrared (AFM-IR) microscopy is a family …
