Multiple chemically modulated capacitance.

摘要

Apparatus and methods are provided for multi­ple detection of analytes employing semiconductor capa­citance as the signal modulated by the analyte. A plu­rality of semiconductor capacitors (20) are organized for detection (at individual sites) of changes in capacitance which are related to changes in a fluid medium, where the change can be related to the presence of an analyte in a channel (16) between the capacitors and a plate (14).

Specific bonding compounds (24) may be placed adjacent some or all of the capacitors on a surface coating (22).
