Tailoring the Swelling‐Shrinkable Behavior of Hydrogels for Biomedical Applications

Advanced Science, Год журнала: 2023, Номер 10(28)

Опубликована: Авг. 6, 2023

Hydrogels with tailor-made swelling-shrinkable properties have aroused considerable interest in numerous biomedical domains. For example, as swelling is a key issue for blood and wound extrudates absorption, the transference of nutrients metabolites, well drug diffusion release, hydrogels high capacity been widely applicated full-thickness skin healing tissue regeneration, delivery. Nevertheless, fields adhesives internal soft-tissue healing, bioelectronics, non-swelling play very important functions owing to their stable macroscopic dimension physical performance physiological environment. Moreover, negative behavior (i.e., shrinkage) can be exploited drive noninvasive closure, achieve resolution enhancement hydrogel scaffolds. In addition, it help push out entrapped drugs, thus promote release. However, there still has not general review constructions applications from viewpoint properties. Therefore, this summarizes tactics employed so far tailoring applications. And relatively comprehensive understanding current progress future challenge different features provided potential clinical translations.
