    Abstract: A novel formulation having anti-viral and spermicidal properties has been developed. The formulation contains lipid vesicles having an outer bilayer formed of a non-ionic amphiphile, a surfactant such as having spermicidal and/or anti-viral activity, an oil and a sterol. The selection of the components making the vesicle is such that the formulation provides rapid spermicidal or anti-viral activity. The formulation and methods of the invention are particularly useful in the mucous membranes such as the vaginal tract and has been tested against viruses such as HIV and Vaccinia.

    Abstract: The present invention relates to micellar nanoparticles and methods of their production. Micellar nanoparticles are made by hydrating a mixture of an oil, a stabilizer/surfactant, and an alcoholic initiator with an aqueous solution. These micellar nanoparticles are normally less than 100 nanometers in diameter. The micellar nanoparticles are particularly advantageous in delivering materials such as estradiol topically through the skin because their small size allows easy penetration.
