  • Cell culture vessel and method of production thereof
    Patent number: 9217130
    Abstract: Disclosed is a method of producing a cell culture vessel (10) having a carbon nanotube (CNT) layer (14) on its surface. The method comprises the steps of providing a vessel (12) having a predetermined shape; providing a CNT dispersion of a CNT material composed primarily of CNT dispersed in a dispersion medium at a concentration of not more than 50 mg/L; and forming the carbon nanotube layer (14) on the surface of the vessel (12). The formation of the CNT layer (14) is achieved by alternately repeating a supply step of applying the CNT dispersion solution to the vessel (12) and a drying step of drying the applied dispersion solution one or more times.
