The cutting-edge, high-resolution chemical imaging technique known as nanoscale Fourier transform infrared spectroscopy (nano-FTIR) is unique.
It is applied to categorise and identify various chemical and biological components. By applying to both biological and environmental processes, nano-FTIR may be utilised to assess a wide range of substances, from proteins to minerals, advancing mission.
A variety of biological and chemical samples, including minerals and biostructures, can be used to create maps of their chemical composition and structure using nano-FTIR, which offers vibrational spectral information in the 800 to 4500 cm-1 (13 to 2 m) range and sensitivity down to the molecular level.
The Global Nanoscale FTIR Spectrometer market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
In order to obtain high-resolution spatial distribution of features that are inaccessible via bulk characterization, new AFM-based techniques called nano-FTIR and PeakForce quantitative nanomechanical mapping (PF QNM) can be used on plant tissues.
This can be helpful for identifying alterations in plant cell walls brought on by processing techniques, mutations, or the environment.
Research on sustainable biomass conversion has made substantial use of conventional FTIR, and using this instrument at the nanoscale can reveal significant changes in biomass recalcitrance that are not visible through spectroscopy of bulk biomass.
At the micrometre scale, spatial variations in cell wall polymers like cellulose, hemicelluloses, and lignin can be detected using ultraviolet, infrared, Raman, optical, and fluorescence microscopy.
Nanometer scale resolution of the distribution of lignin can be obtained by TEM imaging of stained or immunolabeled plant tissues.
The optical information on a sample is delivered with nanoscale resolution by the confined nanofocus of an externally illuminated AFM tip, simultaneously with AFM information, on the basis of scattering-type scanning near-field optical microscopy (s-SNOM) principles.
The Fourier transform of the output of an asymmetric Michelson interferometer is used to analyse the scattered light from a broadband source while the tip is positioned at a particular location.
This yields the local nano-FTIR absorption, which has a strong correlation to the traditional FTIR spectrum. Recently, plant cell walls were studied using this nanoscale hyperspectral imaging method.
