“…Table 4 summarizes different stimuli-responsive biopolymers, which are well-suited for biomedical applications, especially TE applications. Beside stimuli-responsive polymers, lipids and hydrogels have been vastly applied as feedstock materials for the 4D bioprinting [277] , [278] , [279] . Additionally, different types of smart hydrogels including peptide, natural and synthetic hydrogels have found their applications in the biomedical sector.…”
