Smart biomaterials and intelligent scaffolds for wound healing in tissue engineering

The complicated procedures of wound healing include multiple interconnected phases, both cellular and molecular, with the objective of restoring and rebuilding the injured tissue. New and inventive materials in tissue engineering and materials science are producing active protective and adaptable wound dressings, whereas traditional wound dressings are passive and protective. These novel materials react to mechanical, metabolic, and bioelectric changes in the environment and wound tissue. By doing so, they emulate the changing extracellular matrix, stimulating angiogenesis, collagen deposition, and re-epithelialization. The stimulation of wound healing and tissue engineering has been the development of smart polymers, bioactive nanocomposites, and biofunctional hydrogels that revolutionize wound care with responsive behaviors to environmental changes of temperature, pH, enzymes, and electrical potential, alongside sustained drug delivery and improved mechanical strength. Also, intelligent scaffolds, designed through advanced additive manufacturing techniques and microfabrication techniques, possess hierarchical structures that optimize routes for cellular migration and vascularization. Innovation in predictive, real-time, and adaptive therapeutic material design and wound care is made possible by the integration of artificial intelligence (AI), computational modeling, and biosensor technologies. Machine learning can be used to anticipate scaffold qualities and possible in vivo results based on biological performance, parameters, degradation rate, and management data. The most recent developments in smart biomaterials and intelligent scaffolds for wound healing are covered in this review, along with descriptions of the different material classes, design approaches, functional mechanisms, AI-related developments in regenerative medicine, and suggested self-regulating systems for intelligent wound care. It discusses the emerging smart wound care systems, anticipated clinical utility, and proposed solutions to translational challenges on self-regulating intelligent wound care systems. The shift of biomaterials from passive healing to self-responsive active healing systems is a remarkable transitioning, which has repositioned smart materials at the forefront of regenerative medicine.
