Abstract:
Atomic force microscopy-based infrared (AFM-IR) techniques have long enabled chemical imaging of surfaces with spatial resolutions down to 10 nm. In this study, we push the boundaries of AFM-IR spatial resolution to the single-nanometer scale, achieving chemical mapping of supramolecular networks at the submolecular level. This breakthrough is made possible by implementing an innovative tapping-mode AFM-IR approach. Such unprecedented resolution opens new horizons for advancements in nanoscience.
