A novel method tracks reaction boundaries in electrophoresis titration sensors, suggesting improved analysis capabilities.

To develop a new contactless method for detecting reaction boundaries in electrophoresis titration sensors.
Developed a contactless scanning method using capacitively coupled conductivity detection.
Analyzed conductivity distribution theoretically during electrophoretic titration.
Evaluated the method using glucose as a model analyte.
Achieved quantitative detection of glucose over a range from 0.2 to 50 mM.
Demonstrated a detection limit of 0.1 mM.
Showed good stability with relative standard deviations between 0.9% and 4.3%.

Dai et al. (2026) studied this question.
