Target detecting device and target capturer, device and method for molecular adsorption or desorption, and device and method for protein detection

摘要

The present invention provides, for example, a target detecting device comprising a target capturer, means for releasing the target capturer, light irradiating means and light detecting means, the target capturer at least partially containing a region interactive with an electrically conductive member, being capable of capturing a target, and being capable of emitting light upon irradiation with light in the case of not interacting with the electrically conductive member, the means for releasing the target capturer serving to release the target capturer from the electrically conductive member by ceasing the interaction between the target capturer and the electrically conductive member, the light irradiating means serving to apply light to the electrically conductive member, and the light detecting means serving to detect light emitted by the target capturer upon irradiation of light applied by the light irradiating means. It also provides a target capturer comprising an interacting section, a capturing section and a light emitting section, the interacting section at least partially containing a region interactive with an electrically conductive member, the capturing section capable of capturing a target, and the light emitting section capable of emitting light upon irradiation with light when the region in the interacting section does not interact with the electrically conductive member.
