A method for producing a carbon nanohorn aggregate including a fibrous carbon nanohorn aggregate, comprising continuously irradiating with laser light a surface of a carbon target containing a metal catalyst such as iron, wherein a laser irradiation position is moved at a constant speed so that a power density of the laser light with which the surface of the carbon target is irradiated is generally constant, and irradiation is moved to a region adjacent to a region previously irradiated with the laser light, in a direction different from a moving and traveling direction of the laser irradiation position at an interval equal to or more than a width of a degradation region formed around the region irradiated with the laser light

The present invention provides methods for uniform growth of nanostructures such as nanotubes (e.g., carbon nanotubes) on the surface of a substrate, wherein the long axes of the nanostructures may be substantially aligned. The nanostructures may be further processed for use in various applications, such as composite materials. For example, a set of aligned nanostructures may be formed and transferred, either in bulk or to another surface, to another material to enhance the properties of the material. In some cases, the nanostructures may enhance the mechanical properties of a material, for example, providing mechanical reinforcement at an interface between two materials or plies. In some cases, the nanostructures may enhance thermal and/or electronic properties of a material. The present invention also provides systems and methods for growth of nanostructures, including batch processes and continuous processes.
