The MF loaded SLN dispersions were prepared using solvent- injection method.[11,12] The lipid phase was prepared by melting lipid and lipophilic surfactant together, i.e., GMS and Tefose-63 respectively. The solution of MF in ethanol was added to the melted lipid phase. This solution was taken in a glass syringe and was injected rapidly into the aqueous phase containing Tween 80 (having same temperature as that of lipid phase) and sonicated for 3 min using Probe Sonicator (Sonapros PR-250, Oscar Ultrasonics, Mumbai). The formed dispersion was stirred under mechanical stirrer (Remi Motors, Mumbai) for 30 min at 400 rpm, to get nanoparticulate dispersion. The composition of different batches is shown in Table 1.
