摘要:
The invention pertains to a biosensor with a chemoreceptor for detecting one or more trace components produced by burning. The chemoreceptor is preferably connected to a semiconductor component via an electrolyte. The biosensor can be designed in such a way that only a small number of insect antenna segments, in particular a single such segment, is connected at one end of the chemoreceptor directly or via the electrolyte to the semiconductor component.

The invention pertains to a biosensor with a chemoreceptor, e.g. an insect antenna, for detecting one or more trace components in air. The chemoreceptor is connected to a semiconductor component preferably via an electrolyte. The biosensor can be constructed in such a way that only a small number of antenna segments, such as a single such segment, are connected directly or via the electrolyte to the semiconductor component at one end of the chemoreceptor.
摘要:
The reactions of single cells to particular substances in their environment can be established by means of signal converters. In a manner known per se, the potential difference between the interior and the exterior of a cell is measured by means of electrodes, whereby the cell is, however, damaged at least in certain places. Conventional methods which permit a recording of a cell reaction without intervening in the cell interior are either complex or limited in response. In a measuring technique, using at least one biological receptor cell, an asymmetric, extra-cellular, electrical potential of the at least one receptor cell is formed, which produces a multi-pole field and said multi-pole field is applied to determining the cell reaction. The asymmetry in the extra-cellular electrical potential of the at least one receptor cell which reacts to environmental changes can be achieved by, for example, embedding the at least one receptor cell in a bedding element which corresponds to the geometrical form thereof.

A device for recording electroantennograms in open air conditions has a vertical main pipe for leading the air to be measured into an analyser and a random controlled regulator (8, 13) which reacts to a control signal and tightly connects a calibrating unit (7) to an inlet hole (9) in the main air pipe (3) depending on the control signal. This allows a great number of dosing pumps to be used per calibrating unit.
