AB Since the introduction of the Green Analytical Chemistry guidelines, there has been an increasingconcern on the sustainability of sample preparation approaches, particularly if considering theyconstitute the most time-consuming step of the analytical method and the main source of laboratorywastes. Among the alternatives explored, it is important to highlight the miniaturization of the extractionmethods, which has been accompanied by the seek of greener solvents and sorbents. Biopolymersemerge as potential candidates to be used as sorbents in microextraction schemes given their biodegradability,versatility, and easily functionalization. This review offers an overview on biopolymers(chitosan, cellulose, alginate, and agarose) in sorbent-based microextraction approaches, paying attentionto the preparation of the sorbent and the format in which biopolymers are incorporated into thesorbent/device, thus implying a specific microextraction approach, their role in the resulting sorbentmaterial, and the reported analytical applications, covering environmental, food, and bioclinical analysis.
