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
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.Nanopartículas estables que comprenden esterol, preferentemente colesterol y un componente de Quillaja saponaria Molina seleccionado de entre ácido de Quillaja y saponina de Quillaja, caracterizadas por que dichas nanopartículas no comprenden un fosfolípido, presentan un diámetro de partícula comprendido en el intervalo de 15 a 25 nanómetros y en las que la proporción de colesterol a saponina de Quillaja es de 1:10 a 10:1, preferentemente de 1:2 a 2:1.
