Abstract:
The present invention relates to a method for manufacturing patterned substrates which patterns a substrate with a carbon nanotube Langmuir-Blodgett (LB) thin film using a micro contact printing method or a lift-off method, and to growth and differentiation control of stem cells using the same. By using the present invention: manufacturing can be simply completed by attaching and detaching a mold; patterns can be formed on curved surfaces so that patterns can be formed on various shaped substrates; and various shaped patterns can be formed so that the method for manufacturing patterned substrates can be applied in various industries. In addition, the present invention controls growth and differentiation of the stem cells through patterning of the carbon nanotube LB thin film so that the stem cells can be grew in short time and differentiation can be enhanced.

Abstract:
PURPOSE: An n-acetylated chitosan-carbon nano-tube complex and a method for manufacturing the same are provided to individualize the complex and to improve the bio compatibility of the complex by applying carbon nano-tube to n-acetylated chitosan. CONSTITUTION: In an n-acetylated chitosan-carbon nano-tube complex, an n-acetylated chitosan is non-covalently bonded with carbon nano-tube. The diameter of the n-acetylated chitosan-carbon nano-tube complex is less than or equal to 10nm. A method for manufacturing the n-acetylated chitosan-carbon nano-tube complex includes the following: Carbon nano-tube is introduced into an N-acetylated chitosan aqueous solution, and an ultrasonic wave is applied to the solution. A centrifugation process is further implemented after the ultrasonic wave applying process. The centrifugation process is implemented at 1000-5000RPM for 3-10 hours. The complex is individualized by the centrifugation process.

PURPOSE: A surface modification method of lithium niobate substrate is provided to increase bonding strength of an organic thin film with lithium niobate substrate through a mixed process of drying and wet surface process. CONSTITUTION: A surface modification method of lithium niobate substrate comprises the following step: activating lithium niobate substrate surface by mix processing dry surface process and wet surface process. The dry surface processing irradiates one of the following: ultraviolet ray (UV), ozone (O3), ultraviolet ray/ozone (UV/O3) and plasma. The wet surface processing dips the lithium niobate substrate which has activated crystal surface into a surface modifying solution which can form a self assembled monolayer(SAM). The surface modifying solution includes a compound which introduces functional group through fixation on the lithium niobate substrate.

Abstract:
PURPOSE: A method for forming patterns using a carbon nano-tube langmuir-blodgett(LB) thin film and the growth and differentiation control of stem cells using the same are provided to pattern the carbon nano-tube LB thin film on a substrate using a micro-contact printing method or a lift-off method. CONSTITUTION: A method for forming patterns using a carbon nano-tube LB thin film includes the following: A carbon nano-tube LB thin film is patterned on a substrate using a micro-contact printing method or a lift-off method. The micro-contact printing method transfers the carbon nano-tube LB thin film to a patterned mold. The transferred thin film is in contact with a substrate in order to transfer the patterned thin film to the substrate. The lift-off method transfers entire carbon nano-tube LB thin film to the substrate and to a patterned mold. The transferred thin film is lifted off from the substrate. Stem cells are cultivated on the patterns of the substrate.
