METHOD OF FORMING PATTERN USING CARBON NANO TUBE LANGMUIR-BLODGETT FILM AND CONTROL OF GROWTH AND DIFFERENTIATION OF STEM CELL USING THE SAME

摘要

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.
