摘要:
A chip arrangement (1) has a substrate board (2) with an opening (3), into which a carrier chip (4) is inserted, which has an electrical or electronic structural component (5). At least one conductor path (7) is integrated into the carrier chip (4), which connects the structural component (5) to the electrical connection contact (8). The carrier chip (4) is inserted into the opening (3) in such a way that its ends project beyond the opposite-facing, flat-sided surfaces (9, 9′) of the substrate board (2), and thereby form overhangs (10, 10′). Here, the structural component is arranged on the overhang (10) projecting beyond the one surface (9), and the connection contact (8) is arranged on the overhang (10′) projecting beyond the other surface (9′), and the conductor path (7) connecting the structural component (5) and the connection contact (8) passes through the opening (3). A seal is arranged between the substrate board (2) and the carrier chip (4).
摘要:
A device (1) functions for treating malignant, tumorous tissue areas. The device has at least one measuring sensor for determining chemical or physical signal patterns in the immediate vicinity of the tumor cells or similar tissue part, a control unit and at least one treatment assembly, which has as an active agent release element for chemically influencing and/or treatment electrodes for physically influencing the tumorous tissue area to be treated. The sensor(s), the active agent release element, and the treatment electrodes are connected to the control unit for a physical and/or chemical treatment of the tumorous tissue area, controlled as a function of the measured values of the tumor cells. The device is constructed in the form of a swallowable capsule or dragée, and a sensor is provided for detecting release parameters. The control unit is designed with a threshold value switch for activating the active agent release element and/or the electrodes when a predetermined target value is exceeded.

A measuring apparatus (1) for measuring physiological and/or chemical and/or physical properties of at least one living cell (3) contains, in addition to further sensors (4.1, 4.2), a plurality of optical sensors (4) on a support (2), particularly a support made of semiconductor material. By means of a controller (6) and a switching facility (8) which are integrated on the same support (2), the individual optical sensors (4) and the further sensors (4.1, 4.2) can be selectively interrogated. An external signal-analyzing facility (7) with a screen represents a sort of near-field microscope.
摘要:
In a process for mixing microdroplets (2a, 2b, 2c), at least two carriers (3a, 3b) are provided whose surfaces (4a, 4b) are each structured in such a way that at least one hydrophilic surface domain (5a, 5b) is delimited by at least one hydrophobic surface domain (6a, 6b). A first microdroplet (2a, 2b, 2c) is disposed on a hydrophilic surface domain (5a) of a first carrier (3a), and a second microdroplet (2a, 2b, 3c) is disposed on a hydrophilic surface domain (5b) of a second carrier (3b). The carriers (3a, 3b), with their first and second hydrophilic surfaces (4a, 4b) facing each other, are positioned adjacent to each other and sufficiently close to each other by being moved toward each other that the microdroplets (2a, 2b, 2c) come into contact with each other.
摘要:
In a method for measuring the concentration of a ligand contained in a sample that is to be tested, at a plurality of test sites that are located on the surface of at least one substrate, in each case at least one receptor that is suitable upon contact with the ligand for specifically binding to said ligand, is immobilized. The sample is brought into contact for a predetermined time with the test sites in such a way that in the sample differently sized diffusion volumes are adjacent to the receptors from which at least one ligand can diffuse to the respective receptor during the predetermined time. After the predetermined time has passed, for each test site a measured signal for the number or density of the binding events at the test site is acquired.
摘要:
A mount for a programmable electronic processing device is disclosed. It is divided into at least a first functional unit (7) and a second functional unit (8) which represent separate, particularly monolithic integrated, components. The first functional unit (7) defines all input and output interfaces of the processing device with respect to their electrical properties. All essential connections of the second functional unit (8) are accessible from outside only via the first functional unit (7). To this end, the first functional unit (7) includes matching circuits which serve to electrically adapt the connections of the second functional unit (8) to the external conditions.

A device (1) serves for conducting investigations on cell specimens, wherein the device has a microtiter plate or similar receiving device with a plurality of individual containers for the cell specimens. Furthermore, a measuring facility for recording changes in individual specimens is provided. On the underside the microtiter plate or similar receiving device has a measuring structure which carries at least one sensor allocated to each receiving vessel. The measuring structure can either be combined with a bottomless upper part of a conventional microtiter plate, or instead it is a semiconductor substrate plate (2) with a plurality of bowl-shaped receptacle depressions (3) situated therein and provided as containers. At least one sensor is allocated to each depression.
摘要:
A measuring device (1) for measuring or investigating physiological parameters using biological cells or chemical and biologically active substances contained in an analyte (2). The measuring device comprises a sensor (4) with an electronic measurement structure (6) located on a substrate (5). Function-specific receptor cells and/or target cells (7) form part of the sensor (4) and are in direct contact with the measurement structure (6). For measurement, the medium under investigation can be brought into contact with the target cells or receptor cells (7). The measuring device (1) is especially compact in its design and facilitates largely feedback-free investigation of biological or chemical components contained in the analyte.
