摘要： A sensor for measuring a protein with a measurement speed improved from a conventional impedance measurement, using a biosensor is provided. The sensor is capable of efficiently and accurately measuring impedance generated by a selective binding to the protein by Fourier-transforming an electric current signal which is obtained by applying a potential signal of a delta function waveform.The device for measuring a protein using a biosensor includes the biosensor including a sample inlet through which a sample is drawn in, a working electrode on which a receptor layer is coated for selective binding to the specific protein in the drawn sample, and a measuring unit including a reference electrode to form a potential difference with the working electrode, a function generator which applies a potential signal in the form of delta function to the working electrode and the reference electrode, and a data processing unit which measures impedance of the working electrode by Fourier-transforming an electric current obtained in response to the delta function waveform.Accordingly, with the device for measuring a protein using a biosensor is capable of measuring concentration of the protein with accuracy, measurement time is shortened and the concentration of protein can be accurately measured by removing the influence of dispersion.
