AI Technical Summary
Existing technologies struggle to effectively extract the specific dielectric relaxation characteristics of target bacterial communities in strong electrolyte environments, resulting in analytical results that are limited by the charge fluctuations of the background environment, leading to baseline drift and false positives.
A dielectric gradient thin film is deposited on the substrate surface to construct a non-equilibrium analytical surface with a gradient distribution of polarization response time constant. By overlapping the polarization frequency window with the dielectric loss peak of the target analyte particles, the mismatch between the polarization response time constant and the migration rate of ions is utilized to trigger a cooperative polarization response to shield background interference signals. The imaginary part change characteristics of the complex impedance are extracted synchronously through the measurement channel and the reference channel. The quantization parameters are calculated by combining the multidimensional parameter correlation between the phase offset and the complex impedance.
It achieves a highly deterministic response to the target analyte in a strong electrolyte environment, shields against background noise interference, ensures logical consistency and high signal-to-noise ratio of the analytical results, and can accurately extract the target signal under low abundance sample conditions.
