抜粋

We herein propose and demonstrate the constant-phase-mode operation of the light-addressable potentiometric sensor (LAPS). The bias voltage applied to the LAPS sensor plate is servo-controlled to maintain the phase of the photocurrent with respect to the light modulation at a constant value. In this new operation mode, the temporal change and the spatial distribution of the potential at the sensing surface can be recorded and converted into the analyte concentration. This LAPS with a constant-phasemode is advantageous due to its wider measurement range and reduction of artifacts.
