摘要:
When probe biomolecules are immobilized on a substrate surface, a surfactant (phase transfer catalyst) is added for reaction, whereby immobilization efficiency of the probe biomolecules and coating uniformity thereof are improved. Consequently, it is possible to dramatically improve quantitativity and reproducibility of the biosensor element.
摘要:
When a biomolecule and a biochemical reactant are detected, a white interference method is used to conduct a noncontact and nondestructive detection, and further to conduct efficient and accurate detection. This method is applied to a biosensor element, whereby non-labeled and noncontact quality control can be achieved.
摘要:
The present invention aims to improve detecting accuracy and reproducibility of a biomolecule sensor. The biomolecule sensor of the present invention includes single probe molecules orderly aligned and fixed on grid points on the surface of a substrate. Accordingly, in the biomolecule sensor of the present invention: probe molecules for detecting a biomolecule are orderly aligned and separately fixed; blocking for preventing non-specific adsorption is applied to a region other than the region of the probe molecules for detecting a biomolecule; and fluorescence enhancement is achieved by metal microparticles.
摘要:
A biosensor is formed by immobilizing metal particles immobilized on a surface of a carrier and immobilizing probe molecules which are modified with fluorescent molecules on the metal particles. A biomolecule is detected at high sensitivity by use of this biosensor and utilizing fluorescence-quenching and fluorescence-enhancement effects attributable to the metal particle. In this way, it is possible to omit amplification of the biomolecule in a specimen and fluorescence-labeling on the biomolecule when detecting the biomolecule with the biosensor. It is also possible to improve quantitative reliability and repeatability of the biosensor.

A microwave transmitting window for a plasma processing device. The window is a body of one or more pieces of the same or different dielectric materials. A surface of the window facing a microwave transmitting horn or waveguide is planar and extends perpendicularly to an axial direction. An opposite surface of the window is recessed such that the body has a non-uniform thickness between the two surfaces. The recessed surface can have various shapes and the overall size of the window can be equal to the size of a plasma formation chamber of the plasma processing device. The outlet of the plasma formation chamber can be formed in an end wall or the outlet can be formed by the inner periphery of the plasma formation chamber.

A vehicle lamp includes: an LED mount on which an LED is placed; an attachment that fixes the LED to the LED mount; a power supply that supplies power to the LED; a first optical member that controls light emitted from the LED; and a second optical member that controls light emitted from the first optical member. The power supply and the first optical member are provided at the attachment.

A screw compressor includes a casing having low and high pressure spaces, a screw rotor inserted in a cylinder part of the casing, and a slide valve disclosed in the cylinder part. The screw rotor has a plurality of helical grooves forming a compression chamber. The slide valve is moveable along an axis of the screw rotor and faces an outer periphery of the screw rotor to form a discharge port to communicating the compression chamber with the high pressure space. Fluid in the low pressure space is sucked into the compression chamber, compressed, and then discharged to the high-pressure space when the screw rotor rotates. The slide valve includes a sealing projection located on a back surface of the slide valve opposite to the screw rotor, and separating the low and high pressure spaces from each other when the sealing projection is in slidable contact with the casing.

An elastic-wave filter device includes a first piezoelectric substrate, a second piezoelectric substrate, a first pillar-like wiring electrode, and a second pillar-like wiring electrode. The first and second substrates have a first and a second IDT electrodes on their top faces respectively. A lateral face of the second substrate confronts a lateral face of the first substrate. The first pillar-like electrode and the second pillar-like electrode are formed above the first and the second substrates respectively, and are electrically connected to the first and the second IDT electrodes respectively. The first substrate is thicker than the second substrate. A distance between a plane including the top face of the first substrate and a plane including the top face of the second substrate is smaller than a distance between a plane including an underside of the first substrate and a plane including an underside of the second substrate.
