Used as a redox-active surfactant in electrochemical sensors and biosensors due to its ability to facilitate electron transfer while stabilizing biomolecules at electrode surfaces. Its dual quaternary ammonium groups enable strong interaction with negatively charged membranes and biomolecules, making it effective in DNA detection and enzyme-based sensing platforms. Also employed in modifying electrodes for improved sensitivity and selectivity in detecting anionic species in aqueous solutions. Shows potential in controlled drug delivery systems where redox-triggered release is desired.
