Cartridge-based dispensing of nanostructure films

A method for transferring nanostructure material to a target object, comprising:

• providing a nanostructure film to at least one side of a flexible substrate;
• spooling the flexible substrate into a roll;
• housing the roll in a portable container that permits the roll to rotate;
• and
• unrolling the roll while maintaining the unrolled flexible substrate in the housing;
• and
• passing the unrolled flexible substrate to present the at least one side of the flexible substrate to an opening in the housing to make the nanostructure film accessible to an outside of the housing to permit transfer of at least a portion of the nanostructure film from the flexible substrate to the target object located on the outside of the housing.

A nanostructure material management system, comprising:

• a portable housing with an opening communicating between an internal and an external region of the housing;
• a roll of flexible substrate including a nanostructure film with aligned nanostructures on at least one side of the flexible substrate, the roll being positioned within the housing to permit rotational movement of the roll;
• and
• the roll being arranged and configured to permit the flexible substrate to be unrolled from the roll and, while maintaining the unrolled flexible substrate in the housing, present the at least one side to the opening to expose the nanostructure film to the external region to permit transfer of at least a portion of the nanostructure film to a target object that is external to the housing, with an alignment of the aligned nanostructures being maintained with the transfer.
