ANFF-Q will be hosting a presentation from guest speaker Dr Curtis Marcott, Senior Partner at Light Light Solutions. The presentation will highlight the technical background and applications of nanoscale IR spectroscopy and imaging to the chemical characterisation of nanomaterials, polymers, biomaterials and microelectronics.
Nanoscale IR spectroscopy/imaging offers spectral detection with high spatial resolution beyond the optical diffraction limit (2-5 µm) by exploiting an atomic force microscope (AFM) probe to detect either photothermal expansion force (PTIR/AFM-IR) or near-field scattered IR light via scattering scanning near-field optical microscopy (s-SNOM).
Recent developments in PTIR/AFM-IR and s-SNOM technology have significantly augmented the speed and spatial resolution for chemical analysis. One of the new developments (tapping AFM-IR) allows acquisition of IR images at a specific absorption band simultaneously with sample topography and nanomechanical properties, providing a complete set of topographical, chemical and mechanical insights with ~10 nm spatial resolution. These high resolution measurements are currently accomplished by using high speed tunable laser sources with broad spectral coverage ranging from 670-4000 cm-1, encompassing full capability of traditional FT-IR characterization for dimensions orders of magnitudes smaller than the diffraction limit.
This presentation will be followed by an afternoon tea and general Q&A session.
