PREPARATION METHOD OF CARBON NANOTUBE ARRAY USING NANO-PATTERN OBTAINED BY SELF-ASSEMBLY OF ORGANIC SUPRAMOLECULE AND UV ETCHING, AND PREPARATION METHOD OF CARBON NANOTUBE BIO-NANOARRAY USING THE CARBON NANOTUBE ARRAY
PREPARATION METHOD OF CARBON NANOTUBE ARRAY USING NANO-PATTERN OBTAINED BY SELF-ASSEMBLY OF ORGANIC SUPRAMOLECULE AND UV ETCHING, AND PREPARATION METHOD OF CARBON NANOTUBE BIO-NANOARRAY USING THE CARBON NANOTUBE ARRAY
PURPOSE: A method for preparing a carbon nanotube (CNT) array, a method for preparing a CNT bio-nanoarray, and a method for detecting the reaction of a biomaterial and a bio-receptor by using the CNT bio-nanoarray are provided, to allow a nano-sized pattern to be formed by simple several steps of process and to allow the orientation of microstructure to be controlled easily. CONSTITUTION: A carbon nanotube array is prepared by forming a thin film of a self-assembling organic supramolecule on a substrate; annealing it to form a cylindrical regular structure by the self-assembly of the organic supramolecule; irradiating a UV ray to the structure to decompose the center part where a carbon chain is concentrated to form a nano-pattern of an organic supramolecule; etching it by using the nano-pattern as a mask to form a nano-pattern on a substrate; and arraying a carbon nanotube on the nano-pattern. Preferably the organic supramolecule is a disk-type or dendrimer fan-shaped organic supramolecule. Preferably the organic supramolecule is represented by the formula 6 or 7. A CNT bio-nanoarray is prepared by adhering a biomaterial or a bio-receptor to the CNT array obtained by the method.
