1. A nanocluster in which carbon nanomaterials covalently bonded to a C8-C14 alkyl group or a C8-C18 alkenyl group, and further covalently bonded to a polyalkylene glycol are self-assembled by non-covalent bonding,
wherein the C8-C14 alkyl group or the C8-C18 alkenyl group is located within the nanocluster and on a surface of the nanocluster,
wherein the polyalkylene glycol is located on the surface of the nanocluster,
wherein an average particle diameter of primary particles of the carbon nanomaterials covalently bonded to the C8-C14 alkyl group or the C8-C18 alkenyl group and the polyalkylene glycol is from 1 to 12 nm, and
wherein an average particle diameter of the nanocluster is from 30 to 500 nm.
