Claim:
1. A non-optical chemical sensor system, comprising: a sensor structure having a surface, said sensor structure configured to measure a distance of a label from said sensor structure surface based on a change in frequency associated with the sensor structure; a tether comprising a probe strand of a chemical substance having binding sites disposed along a length of said probe strand, said probe strand having a first end attached to said surface of said sensor structure and having a second end; a control and analysis module connected to said sensor structure, said control and analysis module configured to control a non-optical measurement signal applied to said sensor structure and to analyze a measurement signal generated by said sensor structure; and said label, wherein said tether is configured to tether said label to said sensor structure surface in the presence of a target chemical compound, and wherein said sensor structure is configured to non-optically sense said label; wherein said control and analysis module is programmed to provide a measurement result indicative of the presence of said target chemical compound, said measurement result based on a first measurement of a distance of said label from said surface of said sensor in the absence of said target chemical compound and a second measurement of said distance of said label from said surface of said sensor in the presence of said target chemical compound.
