Schematic diagram of the optical system for laser irradiation, where ϕ and f indicate the diameter and focal length, respectively. Light was guided through an optical fiber and the exit surface of the fiber was projected on the bottom of the 96-well cell culture plate by an aspheric lens. Power density was adjusted by the variable attenuator. The position of the cell culture plate was controlled by a two-axis motorized linear stage. The temperature of the well plate was kept at 37 °C using a plate warmer
