Our research has a focus on valorizing plant biomass from the tropical biodiversity. For that, it's very important to characterize well those materials so we can give the best value to them and propose the best destinations. For that, in this work, we employ the MALDI imaging mass spectrometry analysis as a characterizing technique because it's a very precise method that can give us a molecular-specific imaging of the biological tissue.
With the results, we can have a overview of the main components of this plant biomass and also their localization, and this can guide our exploration of new products and processes from that material. However, to have a very good MALDI image mass spectrometry analysis, it's very important to have a good sample preparation method, and that's exactly what we describe in this work. Advancements in technology have led to many challenges in imaging mass spectrometry analysis.
Plant tissues, in particular, pose a complex challenge due to their specialized organs. It's crucial for this technique, this sample preparation, if the sample preparation is done inadequately, the signals won't be detected or artifacts will appear, leading to inaccurate results. These protocols allow us the preparation of thin slice of gut-resistant palm seeds, serving as a proof of a concept for molecular mapping within a live seed tissue.
So this technique offers valuable insights into oligosaccharides present in these seeds. So we hope that technique will be helpful for the researchers with similar obstacles. This technique can help on the study of other hard seeds or any other biological material that imposes a challenge to be cut into fin slices.
For example, this protocol can be a tool on the study of seed development and germination if one is studying a hard seed.
