Par contre, dans cette étude Lien, aussi publiée en 2015, ils utilisent des nanoparticules de silicium poreux.
"Porous silicon (PSi) displays many advantageous properties that render it as a potential theranostic vector in biomedical applications, such as high biocompatibility, capability to increase the dissolution rate of poorly water-soluble drugs, high drug loading capacity, and tunable surface chemistry."
