Nanoparticles, procedure for preparing and using them as carriers of amphipathic or hydrophobic molecules in the medical field, including cancer treatment, and food-type compounds

摘要

Stable nanoparticles comprising sterol, preferably cholesterol and a component of Quillaja saponaria Molina selected from Quillaja acid and Quillaja saponin, characterized in that said nanoparticles do not comprise a phospholipid, have a particle diameter in the range of 15 to 25 nanometers and in which the ratio of cholesterol to Quillaja saponin is 1:10 to 10: 1, preferably 1: 2 to 2: 1.
