Recent applications of infrared (IR) and Raman chemical imaging in plant materials

Applications of infrared spectroscopy in polysaccharide structural analysis: Progress, challenge and perspective

“…FTIR microspectroscopic imaging is a label-free imaging technique which can not only identify polysaccharides in PCW but also determine their spatial distribution and relative abundance ( Türker-Kaya and Huck, 2017 , Zhao et al, 2019 ). Based on the non-destructive character, it is capable of studying polysaccharides in PCW in situ during different periods or in different environments ( Wu et al, 2019 ).…”

“…Applications of IR spectroscopic methods in cellulose analysis in both isolated state and plant cell wall (PCW) were discussed by Makarem et al (2019) . There were also some reviews about IR imaging of polysaccharides in PCW ( Gierlinger, 2018 , Kumar et al, 2016 , Wu et al, 2019 ). However, these papers are more specific to only one application filed rather than comprehensive.…”
