This chapter is dedicated to the possibility of combining Raman spectroscopy with other spectroscopic methods, namely laser-induced breakdown spectroscopy (LIBS) in the detection and characterization of microplastics embedded in tissues of selected model organisms. The idea is to take advantage of the complementarity of the two methods, which originates in the way of laser-tissue interaction that both techniques utilize for sample analysis. Their joint use yields complete chemical information, that is, Raman spectroscopy 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 of the sample. Moreover, these two methods need very similar components and thus can share the majority of the laboratory setup. The chapter gives an overview of hyphenated Raman and LIBS systems, advancements in this field, and options for data processing of joint Raman and LIBS analyses. Data fusion of Raman spectroscopy and LIBS is also discussed. Special attention will be given to the detection and characterization of microplastics using Raman and LIBS systems, as microplastic pollution has attracted considerable attention in recent years, with news of microplastic detection in recent areas and also in human bodies resonating publicly. Raman spectroscopy may be utilized in the detection of microplastics and recent works support this. With the help of LIBS, which can elucidate further the potential risks of weathered microplastics, the hyphenated approach may be the way forward for in situ detection and characterization of microplastics.
