    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.

    摘要: Provided are a biochip and a method of detecting a reaction from the biochip. This method includes preparing a first mixture solution of polyvinylpyrrolidone (PVP) and a sample including target molecules, measuring absorbance or transmittance of the first mixture solution, preparing a second mixture solution including the PVP, the sample, and a receptor of the target molecules, measuring absorbance or transmittance of the second mixture solution, and calculating an absorbance or transmittance difference between the first mixture solution and the second mixture solution. Thus, it is possible to reduce the production cost of the biochip by inducing a reaction of an antigen and an antibody using PVP. Further, it is possible to detect an accurate quantity of the antigen by analyzing a quantity of antigen on the basis of the absorbance or transmittance difference.
