Dear Sir.

Your concerns are really genuine.

From onward, we will also explore additional options for the impedance analyzer, such as measuring resistance, capacitance, and reactance of the sensors, if these options are available in addition to impedance and phase angle.

Our process involves flowing the sample and antibody through the device, allowing them to dry, and then taking measurements with the impedance analyzer. The amplitude of the signal is fixed, and we vary the frequency from 100 Hz to 1 MHz using the impedacne analyzer. When we reach a frequency of 1 MHz for my sensor, the impedance drops to less than 4-5 MΩ, and the angle changes to -52 degrees.

Best regards,
