Abstract: An antimicrobial device (50) includes an antimicrobial unit (60), an ion unit (70), and a control unit (80). The antimicrobial unit (60) delivers at least one of light having an antimicrobial effect, a gas having an antimicrobial effect, or liquid particles having an antimicrobial effect toward a target space (14). The ion unit (70) delivers ions toward the target space (14). The control unit (80) controls the antimicrobial unit (60) and the ion unit (70). Each of the antimicrobial effect of the light, the antimicrobial effect of the gas, and the antimicrobial effect of the liquid particles is stronger than an antimicrobial effect of the ions.

Abstract: A medical device according to the present invention is a medical device that includes an ion generating unit configured to generate a positive ion and a negative ion by discharge, and that prevents or treats a cataract by delivering the positive ion and the negative ion to a surface of an eye.

Abstract: A transport container is a transport container for transporting a biological component being a cell or a collection of cells, and includes an ion generation device configured to generate a discharge product inside the transport container by discharge.

Abstract: Provided are such features as a cell culturing method capable of continuously culturing cells. A workroom (40) includes an ion generator (47) supplying positive and negative ions into a work space (48).

Abstract: Provided is a favorable effect on the mental state of a user who are in a target space that is to undergo climate-control, through ion release. An ion generator (100) causes the target space to have an ion density of 50.000 or more ions/cm3.

Abstract: Each of first to fourth needle-like electrodes is arranged such that a direction of extension thereof is parallel, and generates ions by discharge. Through a space, a gas for conveying the ions generated by the first to fourth needle-like electrodes flows. Needle tips of the first needle-like electrode and the second needle-like electrode protrude from a first wall surface that forms the space, are spaced apart from each other, and are arranged in line in the space. Needle tips of the third needle-like electrode and the fourth needle-like electrode protrude from a second wall surface that forms the space and faces the first wall surface, are spaced apart from each other, and are arranged in line in the space. The first needle-like electrode and the fourth needle-like electrode generate positive ions, and the second needle-like electrode and the third needle-like electrode generate negative ions.

Abstract: Plant growth is promoted by a simple method. A plant (10) is irradiated with a positive ion and a negative ion.
