Varsha Khare opened the discussion of the paper by Pulickel M. Ajayan: The environmental applications of graphene based materials in terms of heavy metal detoxication and particularly the aspect of recyclability, different micro-structures of graphene and doping using solution chemistry leads to better absorption efficiency and recyclability.

Philip Davies said: Could you comment on the present state of knowledge of the interface between carbon nanomaterials and other components.

Pulickel Ajayan responded: This is still a big challenge in my opinion. There has been quite a few single nanotube studies on pull-out from polymer matrices and several of these studies have shown that the interface between nanotubes and polymers can be made strong via chemical modification of the nanotube surface (via covalent or non-covalent functionalization). Relatively limited number of studies have focused on interfaces between nanotubes and metal matrices or nanotubes and ceramics. The electrical contacts between nanotubes and metals have been studied in detail, some leading to good ohmic contacts. The characterization of such interfaces via direct microscopy or spectroscopy has not been very successful.

Thanh Nguyen asked: Could you please comment on the potential biomedical applications of these carbon nanomaterials?
