Multifunctional applications of hydrogel materials in myocardial infarction treatment: from tissue repair to microenvironment regulation

), electrical conduction, immunomodulation, detection, tissue engineering, and microfluidic functions. In terms of drug delivery, hydrogels are able to precisely deliver drugs, stem cells and exosomes to improve the microenvironment of the infarcted area through their controlled release properties. In the field of electrical conduction, hydrogels are used as scaffolding materials that mimic the mechanical and electrical properties of myocardial tissues. The role of hydrogels in immunomodulation has also attracted much attention. In addition, the application of hydrogels in biosensing and detection functions provides new strategies for real-time monitoring of MI. In summary, hydrogels have demonstrated multifunctional advantages in MI therapy, but their clinical applications still face challenges, such as the long-term biocompatibility of the materials and the feasibility of large-scale production. Future research should focus on optimizing the design of hydrogels for more precise treatment and wider applications.
