Abstract: A sensor device according to the present technology includes a stack sensor. The stack sensor includes a first sensor layer and a second sensor layer. The first sensor layer has, as a detection target, a first substrate in a culture solution, the first substrate being changed in accordance with a change in a state of a cell. The second sensor layer has, as a detection target, a second substrate in the culture solution and is provided on the first sensor layer, the second substrate being changed in accordance with the change in the state.

Abstract: A sensor device according to an embodiment of the present technology includes a sensor head and a measurement unit. The sensor head includes a first probe and a second probe, the first probe including a first antenna section used for transmission, the second probe including a second antenna section used for reception, the second probe being situated at a specified distance from the first probe and facing the first probe. The measurement unit includes a signal generator that generates a measurement signal that includes information regarding characteristics of a propagation of an electromagnetic wave in a medium between the first and second antenna sections.

Abstract: Provided is a material-fixing substrate that does not have to use copper as a catalyst because the substrate-bonding site includes a cyclic alkyne to form a covalent bond with a surface of the substrate, and therefore that can reduce damage to a cell, for example, in a case where a to-be-fixed material is the cell. The material-fixing substrate has a to-be-fixed material fixed thereon via a material-fixing agent. The material-fixing agent includes: a substrate-bonding site that forms a covalent bond with a surface of the substrate and includes at least a cyclic alkyne; a hydrophilic site that is bonded to the substrate-bonding site; a light-responsive site that is bonded to the hydrophilic site and changes the skeleton thereof by irradiation with light; and an attachment site to which the to-be-fixed material is attached.
