  • Publication number: 20250003949
    Abstract: A cell sample measurement apparatus includes a sample stage for placing an object cell sample containing a plurality of cells cultured on a culture dish, an evaluation light irradiation unit for irradiating N irradiation regions set by dividing a culture region in the object cell sample with evaluation light having a wavelength in a mid-infrared region with irradiation amounts different from each other, a dead cell number measurement unit for measuring a dead cell number generated according to the irradiation amount of the evaluation light in each of the N irradiation regions, and a culture state analysis unit for obtaining, for the object cell sample, an object correlation between the irradiation amount of the evaluation light and the dead cell number for the N irradiation regions serving as an index of evaluation of a culture state of the object cell sample.

  • Publication number: 20250002836
    Abstract: A cell sample evaluation apparatus includes an evaluation light irradiation unit for irradiating an irradiation region set in a culture region of a plurality of cells in an object cell sample with evaluation light having a wavelength in a mid-infrared region under a predetermined irradiation condition, a dead cell number measurement unit for measuring a dead cell number generated according to an irradiation amount of the evaluation light in the irradiation region of the object cell sample, and a culture state analysis unit for evaluating a culture state of the object cell sample by obtaining an object correlation between the irradiation amount of the evaluation light and the dead cell number for the object cell sample and comparing a reference correlation between the irradiation amount of the evaluation light and the dead cell number for a reference cell sample and the object correlation.

  • Publication number: 20240319202
    Abstract: A method for evaluating an aggregation state of aggregative proteins in a solution is disclosed, the method comprising evaluating an aggregation state of aggregative proteins using, as an index, light-absorption/fluorescence characteristic(s) of a certain xanthene dye in a solution comprising the aggregative proteins and the xanthene dye or a salt thereof.

  • Publication number: 20110285043
    Abstract: In a dissolving step, a poorly soluble drug and a dispersion stabilizer are dissolved in a volatile organic solvent. In a fixing step, the organic solvent, contained in a solution obtained in the dissolving step, is removed by evaporation, pellet-form residues 1 are obtained by the organic solvent removal, and the residues 1 are fixed on respective bottom surfaces of a plurality of locations of a container 30. In a water injecting step, water 2 is injected into each of a plurality of recesses 31 of the container 30. In an irradiating step, laser light L, emitted from a light irradiating unit 20, is irradiated simultaneously or successively on the residues 1 fixed on the respective bottom surfaces of the recesses 31 of the container 30, and the residues 1 are thereby pulverized and made into microparticles and a microparticle dispersion liquid, constituted of the microparticles being dispersed in the water 2, is manufactured.
