Abstract: An assembly for optical preconditioning of an optically activatable biological sample comprising of cells suspended in a liquid, with a reservoir which stores the sample from which the sample are conveyed a conveying unit through a hollow channel sequentially one after the other. An illumination unit illuminates the cells contained in the sample which flow through the hollow channel at a flow rate that can be specified by the conveying unit as set by a controllable illumination intensity and illumination period and at least one of a cell analysis and sorting device in fluid communication downstream of the hollow channel.

Abstract: The invention relates to a device (1) and a method for the optical stimulation of an optically activatable biological sample (3), comprising at least one light source (13; 13?, 13?), which emits light of at least one predetermined wavelength that impinges directly or indirectly on the sample (3). The invention is characterized in that: the at least one light source (13; 13?, 13?) is thermally coupled to a hollow channel section (4); the hollow channel section (4) is part of a fluid circuit through which fluid flows; a temperature-control unit (12) and a conveying pump are arranged along the fluid circuit; and the hollow channel section (4) has at least one limiting wall (5) onto which the optically activatable biological samples (3) are thermally coupled in a direct or indirect manner.
