Several materials are used in nano-scale sealing, each chosen for its unique properties. Graphene, for instance, is prized for its strength and impermeability, making it an excellent choice for creating ultrathin, durable seals. Carbon nanotubes are another popular option due to their exceptional mechanical properties and chemical resistance. Polymers such as PDMS (Polydimethylsiloxane) are also widely used because of their flexibility and ease of integration into various systems.
