Abnormal electrical activity of the heart following myocardial infarction (MI) may lead to heart failure or sudden cardiac death. Graphene-based conductive hydrogels can simulate the microenvironment of myocardial tissue and improve cardiac function post-MI. However, existing methods for preparing graphene and its derivatives suffer from drawbacks such as low purity, complex processes, and unclear structures, which limiting their biological applications.
