    L\u2019\u00e9tude 2010 a con\u00e7u des nanoparticules d\u2019environ nm 400 et les a plac\u00e9es dans un hydrogel d\u2019alginate\/chitosane destin\u00e9 \u00e0 \u00eatre lib\u00e9r\u00e9 dans le c\u00f4lon.

    Une page 2026 FDA identifie les informations manquantes sur l'exposition humaine et la s\u00e9curit\u00e9, notamment si KPV pourrait causer des dommages lorsqu'il est administr\u00e9. Cette fronti\u00e8re officielle devrait accompagner toute discussion sur des d\u00e9couvertes cellulaires ou animales prometteuses.<\/p>
