Hyphenated Raman and laser spectroscopy for the characterization of microplastics in tissues

Hyphenated Raman and laser spectroscopy for the characterization of microplastics in tissues

Kapitola, resp. kapitoly v odborné knize

This chapter is dedicated to the possibility of combining Raman spectroscopy with other spectroscopicmethods, namely laser-induced breakdown spectroscopy (LIBS) in the detection and characterization ofmicroplastics embedded in tissues of selected model organisms. The idea is to take advantage of thecomplementarity of the two methods, which originates in the way of laser-tissue interaction that bothtechniques utilize for sample analysis. Their joint use yields complete chemical information, that is, Ramanspectroscopy provides molecular information, whereas LIBS provides atomic information as is well-described in the literature. Ultimately, the tandem LIBS–Raman analysis can be done from the same spot ofthe sample. Moreover, these two methods need very similar components and thus can share the majority ofthe laboratory setup. The chapter gives an overview of hyphenated Raman and LIBS systems, advancementsin this field, and options for data processing of joint Raman and LIBS analyses. Data fusion of Ramanspectroscopy and LIBS is also discussed. Special attention will be given to the detection and characterizationof microplastics using Raman and LIBS systems, as microplastic pollution has attracted considerableattention in recent years, with news of microplastic detection in recent areas and also in human bodiesresonating publicly. Raman spectroscopy may be utilized in the detection of microplastics and recent workssupport this. With the help of LIBS, which can elucidate further the potential risks of weatheredmicroplastics, the hyphenated approach may be the way forward for in situ detection and characterization ofmicroplastics.
