“…From a materials perspective, many of these revisions gave special emphasis to hydrogel bioinks [ 18 , 35 , 36 , 50 , 52 , 53 ] and to natural materials-based bioinks [ 33 , 38 ]. Moreover, recent reviews have also focused on the use of specific polysaccharides to produce bioinks, namely alginate [ 29 , 33 , 37 , 38 ], (nano)cellulose [ 32 , 35 , 40 , 41 , 46 , 47 , 49 ], chitosan [ 44 ], and hyaluronic acid [ 31 ]. Most recently, Mahendiran et al [ 37 ] provided an overview of 3D printing technologies and the use of different plant-based bioinks in tissue engineering, focusing on plant polysaccharides of terrestrial (starch, nanocellulose, and pectin) and marine (ulvan, sodium alginate (commonly referred as alginate), fucoidan, agarose, and carrageenan) origins [ 37 ].…”
