dc.description.abstractMolecular interactions between indole derivatives and 1,2-di-oleoyl-sn-glycero-3-phosphocholine (DOPC) were studied using a Nima Langmuir-Blodgett (LB) trough. A 0.25 M phosphate buffer sub-phase was used with a physiological pH range of 7.31-7.48. The air-phosphate buffer interface was examined at room temperature. Constant ionic strength was maintained by 0.100 M potassium chloride (KCl). Two different indole derivatives were used, indole and tryptophan, in concentrations of 3.0 uM and 5.0 uM. It is evident when examining the isotherms that the DOPC monolayer is expanded in the presence of indole derivatives, as the area per molecule was increased by 0.02nm2/molecule.en
