Zeta potential and zeta size of solid lipid nanoparticles. (A) Zeta potential of blank solid lipid nanoparticle (-14.1 mV) and (B) zeta potential of diosgenin incorporated solid lipid nanoparticles (-26.0 mV) depicting stability. (C) Zeta size of blank solid lipid nanoparticles (436.5 nm) and (D) zeta size of diosgenin incorporated solid lipid nanoparticles show average size range. SEM images of blank and diosgenin loaded solid lipid nanoparticles were taken at × 20,000 magnifications with size ranging up to 200 nm. (E) Blank solid lipid nanoparticles. (F) Diosgenin incorporated solid lipid nanoparticles.
