    摘要: A biosensor reader and a biosensor reader system are provided. The biosensor reader has a field-effect transistor (FET) biosensor attached thereto, and the FET biosensor includes between electrodes a probe channel to which probe materials are immobilized. The biosensor reader analyzes an electrical conductivity change of the probe channel caused by the binding between the probe material and a target material contained in an analysis solution. The biosensor reader includes a measurement module and an output module. The measurement module connects the probe channel electrically to a reference resistance with a fixed resistance value by the attachment of the FET biosensor, measures a reference voltage drop across the reference resistance and a channel voltage drop across the probe channel, and analyzes an electrical conductivity change of the probe channel from the reference voltage drop and the channel voltage drop. The output module outputs the analysis result of the target material according to the electrical conductivity change.
