Abstract: The present invention fundamentally differs from conventional methods in which an external force is directly applied to a surface of an article to be modified, and relates to a method of hydrophobilization (increasing a contact angle of water) which comprises bringing a hydrophobilization substance (a substance for increasing a contact angle of water) released from a material of another location into contact with a surface of an article, especially an article surface being hydrophilic (having a small contact angle of water) in its initial state without applying an external force on the article surface, further a method of control being capable of noncontact switching of a contact angle of water, which comprises conducting hydrophilization of an article surface subjected to hydrophobilization by the above-mentioned method in a noncontact manner and repeating these hydrophobilization and hydrophilization, and a method of pattern formation using the mentioned methods.

Abstract: The present invention fundamentally differs from conventional methods in which an external force is directly applied to a surface of an article to be modified, and relates to a method of hydrophobilization (increasing a contact angle of water) which comprises bringing a hydrophobilization substance (a substance for increasing a contact angle of water) released from a material of another location into contact with a surface of an article, especially an article surface being hydrophilic (having a small contact angle of water) in its initial state without applying an external force on the article surface, further a method of control being capable of noncontact switching of a contact angle of water, which comprises conducting hydrophilization of an article surface subjected to hydrophobilization by the above-mentioned method in a noncontact manner and repeating these hydrophobilization and hydrophilization, and a method of pattern formation using the mentioned methods.

Abstract: There is provided a method of controlling a flow of a fluid in a microchannel, in which a part of a surface of the microchannel is a hydrophilization portion comprised of a substance being capable of decreasing a contact angle of water by irradiation of light, and the method comprises (1) irradiating the hydrophilization portion with light to decrease a contact angle of water of its surface (hydrophilization step), (2) releasing a substance for increasing a contact angle of water from a material for controlling a contact angle of water which contains the substance for increasing a contact angle of water which provides a surface having a contact angle of water larger than that of the hydrophilization portion after the decreasing of a contact angle of water (releasing step), and (3) bringing the released substance for increasing a contact angle of water into contact with the surface of the hydrophilization portion to adhere the substance for increasing a contact angle of water to the surface, thereby increasing
