Abstract: A sensor is provided for conversion of chemical and/or biochemical information from an analyte in a sample to an electrical signal. The sensor includes a test cantilever having a base and a deformable part, with a receptor layer for selective uptake of the analyte applied at least atop the deformable part, with a first and second test transducer arranged atop the test cantilever, and a reference cantilever having a base and a deformable part, with a reference layer for selective non-uptake of the analyte applied at least atop the deformable part, with a first and second test transducer arranged atop the reference cantilever. The transducers output an electrical signal corresponding to the occurrence and/or the concentration and/or the amount of the analyte in the sample.

Abstract: A sensor device is provided for the detection of an occurrence and/or a concentration and/or an amount of an analyte in a sample. The device includes a sensor, connection electronics and a housing. The sensor is configured to convert chemical and/or biochemical information from an analyte, preferably a virus, in a sample to an electrical signal. The sensor includes a test cantilever having a base and a deformable part, where a receptor layer for selective uptake of the analyte has been applied at least atop the deformable part. The sensor further includes a reference cantilever having a base and a deformable part, where a reference layer for selective non-uptake of the analyte has been applied atop the deformable part.
