Publication number: 20160082148Abstract: Disclosed is a film which is able to suppress agglutination by being continuously adhered to an adhesion target portion in a biological body while suppressing a position shift. A film includes an adhesive and an adhesion inhibiting layer. The adhesive layer absorbs and maintains a liquid in a plurality of pores which are opened in one film surface and has a capillary force for adhering the adhesive layer to a first-cell group. The adhesive layer is formed of a biodegradable polymer. The adhesion inhibiting layer configures the other film surface, and inhibits adhesion between a second-cell group which is different from the first-cell group and the adhesive layer. In the adhesive layer, the pore is formed not to be penetrated in a thickness direction of the film, and thus the first-cell group and the second-cell group are separated into the one film surface side and the other film surface side.Type: ApplicationFiled: September 11, 2015Publication date: March 24, 2016Applicant: FUJIFILM CORPORATIONInventors: Koju ITO, Souichi KOHASHI, Hidekazu YAMAZAKI, Kenichiro HATA, Katsura SUGAWARA, Eiko GOTO, Masatsugu SHIMOMURA, Hiroshi YABU, Takahito KAWANO

Patent number: 9044899Abstract: A solution of polymer uniformly dissolved into a solvent is prepared in a solution preparing step. The solvent contains good and poor solvent components for the polymer. The solution is discharged from a coating die to a support to be a coating film thereon in a primary body forming step. A water drop generating step and a fluidity decreasing step are performed in parallel with each other while wet air is applied to the coating film. Water drops are generated on a surface of the coating film in the water drop generating step. The good solvent component is evaporated from the coating film to decrease fluidity of the solution for forming the coating film in the fluidity decreasing step. In the water drop evaporating step, dry air is applied to the coating film. The solvent and the water drops are evaporated from the coating film to obtain the porous film.Type: GrantFiled: July 29, 2010Date of Patent: June 2, 2015Assignee: FUJIFILM CORPORATIONInventors: Koju Ito, Hidekazu Yamazaki

Patent number: 8518490Abstract: In a coating zone, a cylindrical tube is soaked in and taken out from a solution, such that a coating film is formed on a curved surface of the tube. In a wet gas zone, while a first gas feeding nozzle having a gas outlet moves in a state where the gas outlet faces an outer peripheral surface of the tube, wet gas is blown toward the coating film through the gas outlet. Water drops are generated on the coating film and grown up. In a dry gas zone, as in the case of the first gas feeding nozzle, while a second gas feeding nozzle having a gas outlet moves, dry gas is blown toward the coating film through the gas outlet. Solvent and water drops are evaporated from the coating film. Pores form from the water drops as a template for the porous material on the coating film.Type: GrantFiled: March 30, 2010Date of Patent: August 27, 2013Assignee: Fujifilm CorporationInventors: Koju Ito, Tsukasa Ishihara, Hidekazu Yamazaki

Patent number: 8357428Abstract: After a second liquid is applied to a support and dried, a first liquid is applied thereon. On a film of the first liquid, a third liquid (water) is supplied in droplets using an inkjet-type liquid supply unit. An area supplied with the droplets is referred to as porous area. Next, an organic solvent is evaporated from the film and the droplets are evaporated from the porous area. Thus, a porous film is obtained. The porous film has the porous areas in which a plurality of pores are arranged. Since the droplets are directly formed by an inkjet printing method, a condensation process and a droplet growing process are unnecessary. Thus, the porous film is produced efficiently. Shapes of the porous areas can be changed easily. The porous areas can be formed on the porous film in various patterns.Type: GrantFiled: March 30, 2009Date of Patent: January 22, 2013Assignee: FUJIFILM CorporationInventors: Koju Ito, Hidekazu Yamazaki

Patent number: 8187852Abstract: A porous film is used as a cell culture substrate that is a scaffold for a spheroid. The porous film has a plurality of pores whose diameters gradually increase in a direction A. The diameters of the pores gradually increase from a first area P1 to a third area P3 in this order. The first to the third areas P1 to P3 are located on the porous film along the direction A. The diameters and depths of the pores increase in proportion to the distance in the direction A.Type: GrantFiled: March 26, 2009Date of Patent: May 29, 2012Assignee: FUJIFILM CorporationInventors: Hidekazu Yamazaki, Tsukasa Ishihara

Publication number: 20110117324Abstract: A hydrophobic liquid containing a dispersion medium and fine particles is prepared. The fine particles have insolubility of a certain level in a predetermined liquid having a hydrophobic character. The hydrophobic liquid is applied to a support to be a film thereon. Wet gas is blown to the film. Water vapor is condensed from ambient air on a surface of the film to generate water drops thereon. A dispersion medium evaporating gas is blown to the film, such that the dispersion medium is evaporated from the film. A water drop evaporating gas is blown to the film, such that the water drops are evaporated from the film. Accordingly, the water drops function as the template for forming pores, such that the pores are formed on a micro protrusion-depression structure constituted by the fine particles.Type: ApplicationFiled: November 15, 2010Publication date: May 19, 2011Applicant: FUJIFILM CORPORATIONInventors: Koju ITO, Hidekazu YAMAZAKI

Patent number: 7871549Abstract: A polymer solution (21) is prepared by dissolving poly-.?.-caprolactone and amphipathic polyacrylamide in an organic solvent. The polymer solution (21) is cast from a casting die (25) onto a casting belt (26) to form a casting film (40). Air (35) from a blowing and suctioning device (34) is sent to the casting film (40) to generate droplets (44). The relative speed of drying air (37) to the moving speed of the casting belt (26) is adjusted at 5 m/min in parallel flow. The water in the drying air (37) is condensed in the casting film (40) to form the droplets (44). The droplets (44) are evaporated after evaporating the organic solvent in the casting film (40), so that a honeycomb-structure film (12) can be obtained.Type: GrantFiled: August 3, 2005Date of Patent: January 18, 2011Assignee: FUJIFILM CorporationInventors: Hidekazu Yamazaki, Koju Ito
