GG's graphene foam is an exceptional substrate material for cell culture. Our studies demonstrated robust attachment of both cardiomyocytes and cardiac fibroblasts without any cell adhesion coating - with no adverse effects on cell viability. This innovative material significantly enhances our cell culture processes, offering promising potential for advanced biomedical and tissue engineering applications.
