Exploring colloidal stability and migration dynamics through integrated photonic into aqueous black carbon dispersion

Abstract
This study investigates the migration and stability of colloidal suspensions (black carbon dispersed in water and water plus SDS) through quasi-surfacic resonant analyses. Sensors, composed of organic UV210 micro-resonators onto oxidized silicon substrate, are integrated into a test platform with real-time detection. Experimentations explore the influence of black carbon nano-powder size and concentration on colloidal dispersion stability. Findings highlight the impact of black carbon concentration on its migration and emphasize the anionic surfactant’s effect on increasing stability. These conclusions, corroborated by rheological and zeta potential measurements, provide insights into determining colloidal dispersion stability and migration via optical resonant analysis.
