Abstract: A method for inspecting probe molecule includes evaluating the formation of the probe molecule at the surface of the graphene by comparing an intensity ratio a1/b1, and an intensity ratio a2/b2. The intensity al is of a peak of the first Raman spectrum having a peak top positioned in a first band of not less than 1200 cm−1 and not more than 1500 cm−1. The intensity b1 is of a peak of the first Raman spectrum having a peak top positioned in a second band of not less than 1510 cm−1 and not more than 1800 cm−1. The intensity a2 is of a peak of the second Raman spectrum having a peak top positioned in the first band. The intensity b2 is of a peak of the second Raman spectrum having a peak top positioned in the second band.

Abstract: A binding capacity evaluation apparatus includes a first solution tank into which a first solution is input, the first solution including a hydrophobic substance and a hydrophilic substance; a second solution tank into which a second solution is input, the second solution including water as a major component; a light irradiation device irradiating light on a third solution including a mixture of the first and second solutions; a light-receiving device receiving light passing through the third solution; and a light transmittance measuring device measuring light transmittance by using an intensity of the light received by the light-receiving device. The apparatus uses the light transmittance to detect when the hydrophobic substance becomes supersaturated in the second solution.

Abstract: According to one embodiment, a sensor element capable of detecting a target substance contained in an atmosphere is disclosed. The sensor includes a graphene, a drain electrode provided on the graphene, a source electrode adhered to the graphene, and a first substance provided on the graphene and having a charge condition. The charge condition is changed when irradiation of light and stopping of the irradiation of the light are performed. The target substance is detectable by measuring current that flows between the source electrode and the drain electrode. The measuring of the current is performed in a period during which the irradiation of the light and the stopping of the irradiation of the light are repeated above the sensor element.

Abstract: According to one embodiment, a method for determining a molecular probe is a method for determining a molecular probe that captures a target compound. The method comprises (S1) making candidate molecules of one kind in contact with a target compound, and electrophoresing an obtained mixture on a gel, and (S2) determining the candidate molecule as the molecular probe that captures the target compound in following case when the band of the candidate molecule is separated into a plurality of bands, or when the candidate molecule forms a broad band in the electrophoresed direction on the gel after the electrophoresing.

Abstract: An image erasing apparatus according to an embodiment includes a sheet supply portion that supplies a sheet and an ejector. A first conveying path conveys the sheet from the sheet supply portion toward the ejector. A reader arranged on the first conveying path reads an image on the sheet. A second conveying path branches from the first conveying path at a downstream of the reader on the first conveying path and merges with the first conveying path at an upstream of the reader on the first conveying path. An erasing unit is arranged on the second conveying path. A conveying path changing portion is arranged at a branching portion. An operating portion receives a setup of the processing to the sheet. A controller changes a conveying path of the sheet in accordance with the setup received by the operating portion before the sheet is supplied from the sheet supply portion.
