Abstract

Cette invention porte sur une nanocapsule de silice utilisable en tant que support pour un système d'administration de médicament, qui a une excellente biocompabilité et permet à un comportement de libération de médicament d'être librement contrôlable dans une diversité de circonstances, et, en outre, adaptable pour une utilisation pour rendre l'eau de rivière ou un fluide corporel inoffensif par confinement de substances nuisibles telles que des ions métalliques lourds ou des radio-isotopes, qui polluent l'eau de rivière, le fluide corporel ou similaire, à l'intérieur de la capsule. La nanocapsule de silice comprend une enveloppe de silice poreuse comprenant de la silice et au moins un composé photodécomposable lié à la silice.
