摘要： Humidity or a gas concentration or a solvent concentration in at least one gas is detected by a field effect transistor-based gas sensor whose sensor signal is generated by the change in the work function on a sensitive film. Detection is to be provided in a simple, effective and inexpensive manner. An additional change in potential is impressed at a gate of the field effect transistor and a variable of the resulting change in the sensor signal relative to the additional change in potential is evaluated. For example, each variable, which is e.g. a ratio, can be assigned a relative humidity, a gas concentration, or a solvent concentration. Sensitive films having at least one polymer are particularly advantageous.

摘要： A biosensor for detecting an antigen using an antigen/antibody coupling includes: a silicon substrate, at least one interdigital electrode pair structure that is located on the silicon substrate, the electrode pair being interspaced at a maximum distance of 1.0 μm; a counter-electrode on the silicon substrate; a reference electrode; a first layer of protein, covering at least the interdigital electrode structure; a selective second protein layer applied to the first layer and containing a capture antibody selected specifically with respect to the antigen of interest and to which the antigen can be coupled. A sensor signal can be read on the interdigital electrode structure, if the antigen is coupled to the capture antibody by way of a sample to be analysed that comes into contact with the biosensor and a redox reactive molecule is enzymatically released on the sensor surface by an enzyme-marked detection antibody likewise coupled to the antigen.
