  • Publication number: 20240409768
    Abstract: Provided is a method of producing a polymer-coated substrate for capturing cancer cells in which a polymer layer is stably maintained on the surface of the substrate for a long time even in a liquid environment. The method of producing a polymer-coated substrate for capturing cancer cells includes forming a polymer layer using a hydrophilic polymer represented by the following formula (I) on a surface of a substrate having undergone anti-reflection treatment, wherein R1 represents a hydrogen atom or a methyl group; R2 represents an alkyl group; m represents 1 to 5; and n represents the number of repetitions.

  • Patent number: 11964517
    Abstract: A tire 12 includes: a tread surface 34; seat contact surfaces 58 each to be in contact with a seat S of a rim R; and side surfaces 60 extending on and between the tread surface 34 and the seat contact surfaces 58. Each side surface 60 includes a flange contact surface 62 to be in contact with a flange F of the rim R, and a flange opposed surface 64 which is located radially outward of the flange contact surface 62 and is to be opposed to the flange F. The flange opposed surface 64 is formed to be a surface having a diameter increasing outward in an axial direction. A shape of the flange opposed surface 64 is represented by a circular arc, and a radius of the circular arc is not less than 11.0 mm and not greater than 20.0 mm.
