Abstract: [Problem to be Solved] Provided is a motile cell sorting device that can effectively sort motile cells, such as sperms, having excellent motility and morphology by performing image analysis when animal cells are sorted. [Means for Solution] The motile cell sorting device 1 comprises a storage unit 3, a first introduction unit (cell injection channel) 5, a first introduction control unit 7, a first holding unit (cell capture area) 9, a first derivation unit (cell collection channel) 11, a first derivation control unit 13, a collection unit (liquid storage) 15, a photographing unit 17, and a first controller 19.

Abstract: A masking member contains parallel through-holes, each of the through-holes contains a tilted wall structure; an upper end of the tilted wall structure of one of the through-holes abuts on an upper end of the tilted wall structure of an adjacent one of the through-holes thereby forming a knife-edge ridge at the upper ends. The masking member may in contact with a substrate. Formation in quantity of various different populations of a substance being studied with multiple combinations of distribution form and distribution density may be conducted by dripping a suspension of a single concentration of the substance onto the masking member.

Abstract: An instrument for fixedly transplanting a living body embryo into a uterus has an instrument, for transplanting the living body embryo into the uterus, which is to be inserted into a uterus and a magnetic embryo accommodation container holding instrument (transferred embryo fixing instrument) to be attached to the living body. The instrument for transplanting the living body embryo into the uterus has an embryo accommodation container having an embryo accommodation part having an embryo insertion portion communicating with outside and a magnetic material and a shaft-shaped container transfer tool for separably holding the embryo accommodation container at its distal end portion. The magnetic container holding instrument has an attaching part to be attached to an epidermis of the living body and a magnet capable of attracting the magnetic material of the embryo accommodation container thereto.

Abstract: Provided is a 3-dimensional confocal microscopy apparatus which is manufactured by combining a confocal microscope and an optical tweezers technique, wherein a pair of lenses for focal plane displacement where one lens is movable in the optical axis direction is arranged between a fixed objective lens and a fluorescent light imaging camera, and the 3-dimensional confocal microscopy apparatus also includes a mean which corrects the aberration of a fluorescent confocal image obtained by the fluorescent imaging camera. Accordingly, it is possible to provide a 3-dimensional confocal microscopy apparatus which can acquire a 3-dimensional image of a specimen during a manipulation of the specimen using optical tweezers without affecting an optical trap.

Abstract: Disclosed is a method for producing a three-dimensional polymer-metal complex microstructure including forming a polymer structure by stereolithography using a photocurable resin having a reactive group X and dipping it in a liquid of a metal-containing nanoparticle having a reactive group X? which is bound to the reactive group X, thereby forming a metal-containing layer on the polymer structure through binding the reactive group X and the reactive group X?. According to this method, it is possible to produce a polymer-metal complex structure having a steric structure and to produce a three-dimensional polymer-metal complex microstructure which does not denature biomolecules in a metal complexation process.

Abstract: [Problems] To provide an aluminum seamless can very excellent in stab resistance, corrosion resistance and productivity by using a resin-coated aluminum sheet. [Means for Solution] A draw-ironed aluminum can having a resin coating on at least the inner surface of the can, wherein the coating resin on the inner surface of the can has a tensile strength of 270 to 420 MPa.
