摘要： In a method for delivering a nucleic acid of the invention, a nucleic acid is introduced into a cell by pressing the nucleic acid supported on a surface of a solid substrate against the cell. According to the method, the nucleic acid can be delivered into the cell simply at a low cost without placing a heavy burden on the cell at a high nucleic acid delivery efficiency. By allowing the surface of the solid substrate to support the nucleic acid in the form of a complex with a polyamine or a cationic lipid and pressing it against the cell, the introduction efficiency into the cell can be further improved. In the invention, by using a nucleic acid useful for gene therapy as the nucleic acid, a high-efficiency device for gene therapy can be obtained.

摘要： An image forming apparatus includes a toner carrier, a toner image forming unit, and a toner concentration sensor. The toner carrier includes a transparent film. The toner image forming unit forms a toner image onto the toner carrier. The toner concentration sensor senses the concentration of toner on the toner carrier. The toner concentration sensor includes first and second light emitting elements and a light receiving element. The light emitting elements each radiate light directly or indirectly to the toner carrier. The light receiving element receives reflecting light originating from the light emitting elements. The first light emitting element radiates light having a wavelength of a predetermined reflectance resulting from direct radiation to the toner carrier. The second light emitting element radiates light having a wavelength that causes a lower reflectance resulting from direct radiation to the toner carrier than a reflectance resulting from radiation to the toner.
