TL;DR: A showcase of interesting and easily available solutions that contribute to faster and better identification of microplastics using Raman spectroscopy and non-conventional Raman techniques (non-linear Raman, hyperspectral imaging, standoff Raman) which permit more advanced applications such as real-time Raman detection and imaging of micro Plastics.

TL;DR: With the combination of two spectroscopic techniques it is possible to identify the principal seaweed colloids in ground seaweed samples as in extracted material, and represents, as accurately as possible, the native composition of the phycocolloids.

TL;DR: The FTIR and FT-RAMAN spectra of carrageenan and agar, obtained by alkaline extraction from different seaweeds, were recorded in order to identify the type of phycocolloid produced, with special emphasis given to the 500-1500 cm(-1) region, which presents several vibrational modes, sensitive to thetype of polysaccharide and to the types of glycosidic linkage.

TL;DR: The nature of polysaccharides (with extraction and without any type of extraction) present in these seaweeds was determined with FTIR-ATR and FT-Raman analysis of extracted phycocolloids and ground dry seaweed as mentioned in this paper.

TL;DR: The mesoporous silica MCM-41 functionalized with a chelating pyrazolylpyridine ligand was used as a support for the immobilization of tris(β-diketonate) complexes Ln(NTA)3 as discussed by the authors.
