Physicochemical investigation of novel biodegradable dicationic ester bonded m-E2-m gemini surfactants with bile salts: Insights from surface tension, dynamic light scattering and fluorescence

- Study of diester bonded gemini surfactants in presence of bile salts.
- Influence of molecular structure of bile salts on the interaction parameter.
- Fixing gemini into bile salts enhances their capacity to accept hydrophobic guests.
- Geminis generate stronger interactions with sodium cholate than sodium deoxycholate.
