Abstract: A microscope system includes a microscope stage having a top surface configured to have a sample carrier arranged thereon, the sample carrier being configured to receive at least one sample. The microscope system also includes an imaging system configured to image the at least one sample. The microscope system also includes an injector configured to inject a predetermined amount of a liquid into the sample carrier by injecting multiple successive and temporally spaced jets of the liquid into the sample carrier, each jet including a predetermined portion of the amount of liquid.

Abstract: A method for optically examining a biological sample includes: preparing a light-activatable specimen including the biological sample; activating a target region of the light-activatable specimen by irradiating activation light into the light-activatable specimen, the activation light being formed by a light sheet that illuminates a plane in the light-activatable specimen, the plane including at least a part of the biological sample; and imaging the plane illuminated with the light sheet.
