| Abstract: | Programmable hydrogels have emerged as a new generation of intelligent biomaterials capable of integrating stimuli-responsiveness, biocompatibility, and regenerative functions for precise drug delivery. Unlike traditional passive hydrogels, these systems utilize dynamic covalent and supramolecular crosslinking to achieve reversible adaptability and spatiotemporal regulation of therapeutic release. This review systematically summarizes the molecular design principles, stimuli-responsive mechanisms (pH, redox, enzyme, thermal, mechanical, and light), and crosslinking strategies that enable programmability and biodegradability within hydrogel networks. The crucial design approaches, including hybrid network architectures, molecular imprinting, and bioresponsive linkers, are highlighted as central to achieving selective and adaptive functionality. Particular focus is placed on multi-stimuli and feedback-controlled systems that coordinate drug release with biological signals to enable autonomous, context-specific therapy. Recent progress shows the integration of molecular imprinting, bioresponsive linkers, and hybrid structures that improve structural stability while maintaining responsiveness. Applications in wound healing, angiogenesis, and tissue regeneration emphasize the role of programmable hydrogels as bio-instructive matrices that modulate the immune response, preserve redox balance, and promote scar-free healing. Furthermore, emerging technologies such as AI-guided material design, 4D bioprinting, and bioelectronic integration are accelerating the development of closed-loop and patient-specific therapeutic platforms. Despite these advances, significant challenges remain, particularly regarding scalability, reproducibility, long-term stability, and the predictability of in vivo performance, which continue to limit clinical translation. Overall, programmable hydrogels mark a significant shift from static carriers to dynamic, self-regulating biomaterials for advanced regenerative medicine. [ABSTRACT FROM AUTHOR] |
