| Summary: | Shape memory polymers (SMPs) are a class of materials capable of undergoing deformation in response to external stimuli, and their unique shape-changing properties offer vast potential for applications in the biomedical field. Based on the dimensionality of the shape memory effect (SME), deformation can be categorized into macroscopic and microscopic levels. Macroscopic deformation enables SMPs to perform functions such as adaptation, filling, and support through overall structural changes. On the other hand, microscopic deformation involves dynamic modulation of the surface morphology of micro- and nanoscale scaffolds, influencing cell morphology and further regulating cell behavior and fate. Whether at the macroscopic or microscopic level, SME significantly enhances the performance of SMPs as tissue scaffolds or medical devices. This review summarizes the progress of SMP applications in the biomedical field, focusing on SME at different dimensional levels, and provides insights into future development directions. |
