    Abstract: An optical detection method and an optical detection device quickly and accurately detects a micro target substance, such as an antigen, with high sensitivity by using an enhanced electric field. The optical detection device includes: one or more light irradiation units; a detection plate having a laminate structure; a prism in close optical contact to a back surface side of the detection plate and having multiple light incident surfaces with different incidence angles; and a light detection unit which is placed on the front surface side of the detection plate and which detects an optical signal from a sample. Light from the light irradiation unit enters the light incident surfaces of the prism at a fixed angle with respect to the front surface of the detection plate, and the light passing through the prism is irradiated from the back surface side of the detection plate under a total reflection condition.

    Abstract: Provided are core-shell particles which are kept stable in a solvent such as water for a long period. Each core-shell particle includes a core which contains a hydrophobic polymer having an anionic group and a shell which contains calcium phosphate. At least one of calcium atoms contained in calcium phosphate is chemically bonded to a functional group derived from the anionic group. In a method of manufacturing core-shell particles each core-shell particle includes a core which contains a hydrophobic polymer and a shell which contains calcium phosphate, the method includes the steps of: mixing a water-soluble organic solution which contains a hydrophobic polymer having an anionic group with a solution which contains calcium ion so as to obtain a first mixed solution; mixing the first mixed solution with a solution which contains phosphate ions so as to obtain a second mixed solution; and stirring the second mixed solution.

    Abstract: A method of manufacturing a semiconductor package and a semiconductor package in which positional alignment between a wafer and a substrate until the wafer is mounted and packaged on the substrate is achieved accurately. A wafer is mounted on a package substrate by using first alignment marks and D-cuts as benchmarks, and then a mold resin layer is formed on the wafer in a state in which the first alignment mark is exposed. A part of the mold resin layer is removed by using the D-cuts exposed from the mold resin layer as benchmarks, so that the first alignment marks can be visually recognized. A second alignment marks are formed on the mold resin layer by using the first alignment marks as benchmarks. A Cu redistribution layer to be conducted to a pad portion is formed on a mold resin layer by using the second alignment marks as benchmarks.

    Abstract: With the conventional optical deflection elements using polarization gratings (PGs), it has been difficult to independently switch multiple optical beams at one time in a variety of angular ranges and angular steps at high speed on the μ-second time scale, and it has been impossible to achieve a highly reliable optical deflection element module capable of operating at different ambient temperatures. Provided is an optical deflection element including: a polarization grating plate having a rectangular or circular segment structure, in which the cycles A of PGs are not uniform within the plate plane and the cycle and/or the rotational direction of a birefringence axis varies; and a phase panel having a segment structure that is accordingly segmented within the same plane are bonded together, wherein their corresponding segments overlap with each other, and optical switches of the polarization gratings are controlled by a voltage change in the phase panel.

    Abstract: The present invention provides a method for producing a cyclometalated iridium complex, the method including producing a cyclometalated iridium complex by reacting a cyclometalated iridium complex raw material including an organoiridium compound with an aromatic heterocyclic bidentate ligand capable of forming an iridium-carbon bond and an iridium-nitrogen bond, and using as the raw material an organoiridium compound including a substructure represented by the following General Formula (1). The present invention is capable of producing a cyclometalated iridium complex with a high yield without by-production of a halogen-crosslinked iridium dimer. (in General Formula (1), Ir represents an iridium atom, and O represents an oxygen atom).
