Extreme Surface Area

A single gram of graphene can have a surface area exceeding 2,600 square meters - larger than a football field. Thi exordinary graphary capacity provides ample space for loading therapeutic agents, imaging probes, and divisiing ligands. In drug delivy, thi means a small compatit of graphene- based carrier can transport a substantial drug payload, potentially reducing the experiency of dosing and minimizinizing systemic side effects.
