摘要： A device (1) for the carrying out of investigations on cell cultures (2) which take place in a liquid culture medium (4). The device possesses at least a receptacle (3) to contain the culture medium (4) including the cell culture (2), wherein one or more sensors (6) for measurement of the cell culture activities is provided and wherein the receptacle (3) has at least an opening for the adding and the removal of liquid culture medium (4) and the like. A separating element (7) can be introduced into the open upper part of the receptacle (3) and can be brought within the said receptacle (3) in a position close to the bottom (5), in which the said separating element (7) makes a boundary forming a partial space (8) which has a small volume in relation to the entire volume of the receptacle (3). Further, a flow channel (9) is provided, which first, communicates with the small volume partial space (8), and second, communicates with the said reservoir (14). This flow channel (9) and/or the sensors (6) are placed in the area of the small volume partial space (8). By means of the capability for adjustment of the separating element (7) as to its distance from the bottom of the receptacle (3), in the neighborhood of the cell culture (2) a microreaction volume exactly fitting the current requirements can be adjusted. By means of the flow channel (9), the cell culture (2) in the small volume partial space (8) stands in fluid communication with that in the reservoir. For the regeneration of the cell culture solution in the small volume partial space, the separating element (7) can be elevated and depressed, or it is possible, to inject into the small volume partial space of the receptacle (3) a quantity of liquid and by means of a through-flow channel. In this case, a convective mixing of fresh and spent medium takes place through the flow channel (9) between the small volume partial space and the reservoir (14).

摘要： A method is provided for measuring a state variable of a biological cell (3) located in a nutrient medium (2) and supported on and adhering to a support area (5). Within the support area (5) for the cell (3) and at a distance from the support area edge, an opening is made in the membrane of the cell (3). The edge of the cell membrane that surrounds the opening and adheres to the support area (5) seals off the liquid found inside the cell (3) from the nutrient medium (2). Through the opening the state variable (2) is measured. An apparatus for performing the method is also provided.

摘要： A device for investigating activities of cell cultures in a liquid culture medium includes a receptacle for the culture medium, and one or more sensors for measurement of cell culture activities. An opening for adding and removing liquid culture medium is provided. A separating element can be placed close to the receptacle bottom, forming a partial space with a small volume relative to the entire volume. A flow channel that communicates with the small volume and the reservoir and/or the sensors are placed in the small volume partial space. By adjustment of the separating element distance from the receptacle bottom, a microreaction volume exactly fitting the current requirements is obtained. For regeneration of the cell culture solution in the small volume partial space, the separating element can be elevated and depressed, or liquid can be injected into the small volume by the through-flow channel, providing convective mixing of fresh and spent medium.

摘要： In a method for producing a sensor arrangement and the resulting sensor arrangement, a sensor is provided on or in a chip and the chip is covered with a protective cover, the cover being an interface between the sensor and the environment. An adhesive layer is provided between the chip and the protective cover, the adhesive layer alone or together with the protective cover being an interface between the sensor and the environment. The protective cover and/or the adhesive layer may have a channel formed therein, the channel functioning as the reception channel for a sensor. In an alternative embodiment, the protective cover placed on a wafer with several chips, and the wafer is cut up to produce the individual chips with the protective cover. Thus, a sensor arrangement may have the protective cover applied to the individual chip after the chip is cut from the wafer, or the protective cover may be applied to the wafer, and the wafer and cover are then cut up into the individual chips and corresponding covers. The channel leading from one side of the arrangement to the sensor may be taken through the adhesive layer, through the protective cover, or through both. A hole may be formed in the protective cover above the sensor, with the sensor lying loosely in the hole. The reaction volume may be determined by the dimensions of the hole.
