چکیده مقاله
Today, the use of nanoemulsions has been considered as penetration enhancers in pharmaceutical applications. In this paper, the structural properties of soybean oil -based nanoemulsion system with Tween80 as the non-ionic surfactants were investigated with molecular dynamics simulation using GROMACS. This system was simulated with the ratios obtained from experiment in 100 nanoseconds. The equilibrium of system was analyzed through the trajectory, the number of clusters, and the radius of gyration. The number of assemblies remained unchanged after 50 ns. Using the free energy landscapes, the most stable shape of assembly, 31, in system was observed asymmetric and non-spherical. The average solvent accessible surface area (SASA) value of the assembly 31 calculated to be 139.73 ± 14.00 nm2. The arrangement of the molecules in the assembly showed that the carboxyl groups (COOH) of oil and the hydroxyl groups (OH) of Tween80 were placed on the surface while the accessible water molecules and the rest of the molecule are located inside the assembly. The results of molecular dynamic simulation studies of these nanoemulsion systems can be used in interpretation of practical applications of them as chemical enhancer and drug carriers.
