摘要： An endoscope 100 includes a first light source 45 that emits white illumination light, a second light source 47 that emits narrow-band light and an imaging section that has an imaging device 21 having plural detection pixels and images a region to be observed. The imaging section is caused to output a captured image signal including both a return light component of the white illumination light from the region to be observed by and a return light component of the narrow-band light the white illumination light. From the captured image signal, the return light component of the narrow-band light is selectively extracted, and a brightness level of the extracted return light component of the narrow-band light is changed by changing a light amount of light emitted from the second light source 47.

摘要： An object of the present invention is to enable simpler operation in real time and culture while removing unnecessary cells from cultured cells for purification in analyzing, fractionating, and culturing the cells alive and to analyze and fractionate desired cells from the cultured cells to increase the purity, recovery rate, and viability of the cells. The present invention employs a cell-adhesive photocontrollable base material, wherein light irradiation causes the bond dissociation of a photolabile group comprising a coumarinylmethyl skeleton to produce the separation of a cell-adhesive material to leave a non-cell-adhesive material. As a result, cell images can be detected and analyzed to obtain the positional information of desired cells. Based on the positional information thus obtained, the cells can be analyzed and fractionated alive.

摘要： In analyzing, fractionating, and culturing cells alive, operations can be more simply made in real time and culture can be performed while removing unnecessary cells from cultured cells for purification. Desired cells are also analyzed and fractionated from the cultured cells to increase the purity, recovery rate, and viability of the cells. A cell-adhesive photocontrollable base material is used in which light irradiation causes the bond dissociation of a photolabile group comprising an O-nitrobenzyl skeleton to irreversibly change the surface of the irradiated portion thereof from that of the cell-adhesive material to that of a non-cell-adhesive material. Cell images are detected and analyzed to obtain the positional information of desired cells. Based on this information, areas among cells and a cell-adhesive photocontrollable material are cut by second light irradiation. On the other hand, the surface of the base material is changed from a cell-adhesive one to a non-cell-adhesive one by first light irradiation to produce the detachment between cells and the base material. This enables cells to be analyzed and fractionated alive.

摘要： The present invention provides a device and method for analyzing the characteristics of a biopolymer with excellent mechanical stability, high spatial resolution and sensitivity using a simple device construction. Specifically, the Raman scattered light of a biopolymer is measured and the properties of monomer units forming the biopolymer are analyzed by using a biopolymer property analysis chip (100a) characterized by comprising: a solid substrate (110); at least one nanopore (120) disposed in the solid substrate (110); and one or more electrically conductive thin films (130a, 130b) disposed on the solid substrate (110). The biopolymer property analysis chip (100a) is characterized in that the electrically conductive thin films (130a, 130b) are disposed partially on the solid substrate (110) where the nanopore (120) is formed and a biopolymer which has penetrated into the nanopore (120) is caused to generate Raman scattered light by means of irradiation with external light.

摘要： A first irradiation portion that radiates white light onto a subject, a second irradiation portion that radiates narrow bandwidth light having a narrower wavelength bandwidth than the white light, and an observation window used to observe the subject are respectively disposed on a leading end surface of an endoscope insertion portion. Each of the first and second irradiation portions includes a pair of irradiation windows for emitting light therefrom. A straight line passing through a center point of the observation window and bisecting the leading end surface is defined as a boundary line. The pair of irradiation windows of the first irradiation portion are disposed on both sides of the boundary line. The pair of irradiation windows of the second irradiation portion are disposed on the both sides of the boundary line. Spectra of lights radiated from the irradiation windows of the second irradiation portion can be changed individually.
