Abstract: PROBLEM TO BE SOLVED: To provide a new method for carrying a substance to the inside and outside of a nanotube which is applicable to a substance to be occluded decomposable without vaporization, does not use a large quantity of a solvent, is low-cost, and has a low environmental load. SOLUTION: By exposing a nanotube and a substance to be occluded in their coexisting state to a carrier vapor, the substance to be encapsulated is carried and occluded in the nanotube. By exposing a nanotube encapsulating a substance to be occluded to a carrier vapor, the substance to be occluded is carried out to the outside of the nanotube. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: A contrast agent characterized in that each of carbon nanohorns forming a carbon nanohorn aggregate has an opening at the side wall or tip, wherein a metal M (at least one metal selected from among paramagnetic metals, ferromagnetic metals, and superparamagnetic metals) or a compound of the metal M is incorporated in or dispersed on each of the carbon nanohorns. A contrast agent characterized in that it contains a Gd oxide. There is provided a contrast agent, which can be mass-produced easily, and satisfies the requirement of low toxicity and enables microscopic diagnoses when used for MRI. A contrast agent characterized in that is contains a carbon nanohorn aggregate.

Abstract: PROBLEM TO BE SOLVED: To provide a carbon nanohorn composite which can prevent corrosion or elution of an included metal, an included its oxide or the like even under an acidic condition or in an organic solvent and maintains electrical conductivity, and whose surface is not oxidized; and to provide a method for producing the same. SOLUTION: A small size opening is formed in each carbon nanohorn, and a metal, an oxide, a functional molecule, or the like is included in the carbon nanohorn. Thereafter, the opening is closed by a heat treatment in vacuum or an inert gas. Thereby, the included substance is shielded from external environment by the carbon nanohorn and stably exists in the carbon nanohorn. COPYRIGHT: (C)2007,JPO&INPIT

IPC: C01B31/02
Abstract: PROBLEM TO BE SOLVED: To provide a carbon nanohorn composite material which can delay the start of releasing of a substance included in a carbon nanohorn from the carbon nanohorn in a solution capable of dissolving the included substance. SOLUTION: A substance carrier has nanocarbon having an inner diameter of 2-5 nm and an opening having a diameter of 1-2.5 nm in a wall surface. A substance-including composite material is equipped with the substance carrier and a first functional substance included in the substance carrier. A substance-including carbon composite material having a cap effect is obtained by further introducing a second functional substance having a diameter smaller than the inner diameter and larger than the diameter of the opening of the substance carrier having the cap effect into the substance carrier of the substance-including carbon composite material.
