Title:
検体センサおよび検体センシング方法
Document Type and Number:
Japanese Patent JP6568126
Kind Code:
B2
Abstract:
A biosensor includes a detection element having an analyte detecting portion which is monotonically increased in mass in response to detection of an analyte; a reference element having a reference measuring portion which exhibits no reactivity to the analyte; a mixer which mixes a detection signal responsive to mass variations in the analyte detecting portion from the detection element and a reference signal from the reference element; a measurement portion which calculates two candidate phase-change values of a positive value and a negative value, from a signal mixed by the mixer in accordance with a heterodyne system, and determines a phase-change value from the two candidate phase change value by judging whether the phase is positive or negative based on temporal changes in signal strength; and a detection amount calculation portion which calculates a detection amount of the analyte based on the phase change value determined by the measurement portion.
