Abstract:
PROBLEM TO BE SOLVED: To provide a cell culture membrane being excellent in long-term storage properties and chemical resistance and having good cell adhesiveness and long-term culture properties, a cell culture substrate, and a production method of the cell culture substrate.SOLUTION: As a cell adhesion layer, a polymer membrane represented by the formula (I) is formed on the base of a cell culture substrate so as to have a thickness of 0.2 μm or more. (In the formula, R1 and R2 represent a -(CH)-NHgroup (where n represents an integer of 1 or more and 10 or less) or H, and at least either R1 or R2 is a -(CH)-NHgroup. Also, l and m is a positive integer representing a polymerization degree.)
Abstract:
PROBLEM TO BE SOLVED: To provide a method which enables the formation of the fine pattern of a reagent or the like at a desired position with good reproducibility. SOLUTION: This manufacturing method of a substrate includes a vapor deposition process for forming a coating film having an amino group on the surface of the substrate by heating a compound represented by the formula (1), wherein (R 1 is -NH 2 or -CH 2 NH 2 and R 2 is -NH 2 , -CH 2 NH 2 or -H) to form a monomer and vapor-depositing the monomer on the substrate. The surface of the substrate has at least a region comprising a first material and a region comprising a second material and the amount of the amino group present on the surface of the coating film having the amino group per a unit area is different between the surface of the region comprising the first material and the surface of the region comprising the second material. The manufacturing method of the substrate is also disclosed. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a lid material which is closed and opened repeatedly, is easily sealed since the lid material has a shape-retaining function, restoration and the like, and is operated with a single hand, and to provide a packaging vessel including the lid material and having a self-standing property. SOLUTION: The lid material for packaging the food has an adhesion part 11 for adhering to the outer circumferential margin of an opening of a food preservation vessel, and recesses 12a and 12b at least in part, each being recessed from the adhesion surface of the adhesion part 11 in the direction to the inside of the food preservation vessel. A three-dimensional shape is formed at least in the opening area by the adhesion part and the recesses 12a and 12b. An uneven structure having one or two or more protrusions 13 is formed on the recesses 12a and 12b. COPYRIGHT: (C)2011,JPO&INPIT
