A method for bulk separation of single-walled tubular fullerenes (100)
based on helicity is provided wherein a solution or suspension of the
single-walled tubular fullerenes (100) is flowed onto a crystalline or
highly oriented substrate (30). The single-walled tubular fullerenes
(100) that flow onto the substrate (30) have a respective longitudinal
axis that is aligned with the flow direction (105). The direction of flow
(105) is oriented at a predetermined angle with respect to a lattice axis
(24) of the substrate (30) for energetically favoring adsorption of a
respective plurality of single-walled fullerenes (100) having a tubular
contour and a selected helicity. Subsequently, the adsorbed single-walled
tubular fullerenes (100) of the selected chirality are removed from the
substrate (30).
