The phenomenon of bioactivity is associated with the formation of acrystallized hydroxyl carbonated apatite (HCA) layer on the bioglass surface, when soaked in a simulated physiological fluid. This layer is similar to the mineral phase of Bone. Synthesized bioglasses have been obtained using organic modifiers instead of mineral modifiers, which are the usual precursors for sol–gel synthesis. Hyperthermia treatment is a method of the cancer therapy using the high temperature up to 43 oC which healthy cells survive but tumor cells can’t resist. The materials used to raise the temperature are called as “thermoseed” and they are ferrimagnetic, ferromagnetic and superparamagnetic particles potentially.

Extra Virgin olive oil contains many antioxidants and vitamin E. Therefore, it is thought to have anti-aging effects. The purpose of this study was formulate and evaluate the physical properties and the antiaging effects of extra virgin olive oil nanoemulsion. Nanoemulsion was prepared by using 5% extra virgin olive oil and various concentrations of Tween 80 (24, 25, 26%) as surfactant and sorbitol (36, 35, and 34%) as cosurfactant. Extra virgin oil nanoemulsion was prepared by spontaneous emulsification technique by the addition dropwise of oil phase to water phase with stirring at 4000 rpm and the result was continued stirring for 6 hours and sonification for 30 minutes to obtaine nanoemulsion. Extra virgin olive oil nanoemulsion was evaluated for particle size, thermodynamic stability, transmision electron microscopy, surface tension, viscosity, and antiaging effect in six volunteers. The results of this study showed that the average particle size of extra virgin oil nanoemulsion using the combination of 25% Tween 80 and 35% sorbitol was 189.82 nm with the range particle size was 67.63–338.93 nm, pH was 6.2, viscosity was 113 cp, surface tension was 46.67 dyne/cm, and no creaming after centrifugation at 3750 rpm for 5 hours. The application of extra virgin olive oil nanoemulsion two times a day on the cheek region of volunteers caused no irritation and increase of skin hydration, the smaller of skin pores, decrease of spots and wrinkles. It is concluded that extra virgin olive oil can be formulated as nanoemulsion dosage form and potentially used as anti-aging.
