Abstract:
1. A cell culture method comprising: emitting light of which light intensity can be regulated; preparing a cell incubator comprising a photocatalytic film consisting of titanium oxide and in which: a culture medium is injected; titanium in the titanium oxide reacts with water in the culture medium, by irradiated light, to form hydroxyl groups on the surface of the photocatalytic film; and the degree of hydrophilicity of the photocatalytic film surface varies depending on the light intensity of the light irradiated; culturing cells on a surface of the photocatalytic film consisting of titanium oxide whose degree of hydrophilicity varies depending on the light intensity; measuring the activity of cells cultured on the photocatalytic film irradiated with the light; and associating the light intensity with the activity of the cells.
