“…[37] Silica NPs are slowly degraded in water by dissolution into biocompatible and bioadsorbed silicic acid products, [38] and silica NPs are renally excreted. [39][40][41] The unique properties of MSN and silica hybrid NPs have been implemented in catalysis, [37,42] separation, [43][44][45] bio-imaging, [33,[46][47][48] and in cargo delivery applications, [34][35][36][37][49][50][51] to name a few. Large-pore silica and silica hybrid NPs have also been designed for biomedical applications.…”

Abstract:The delivery of large cargos of diameter above 15 nm for biomedical applications has proved challenging since it requires biocompatible, stably-loaded, and biodegradable nanomaterials. In this study, we describe the design of biodegradable silica-iron oxide hybrid nanovectors with large mesopores for large protein delivery in cancer cells. The mesopores of the nanomaterials spanned from 20 to 60 nm in diameter and post-functionalization allowed the electrostatic immobilization of large proteins (e.g. mTFP-Ferritin, ~534 kDa). Half of the content of the nanovectors was based with iron oxide nanophases which allowed the rapid biodegradation of the carrier in fetal bovine serum and a magnetic responsiveness. The nanovectors released large protein cargos in aqueous solution under acidic pH or magnetic stimuli. The delivery of large proteins was then autonomously achieved in cancer cells via the silica-iron oxide nanovectors, which is thus a promising for biomedical applications.

“…For example, polypyrrole-graphene oxide-Fe 3 O 4 magnetic composites were used for the Cr(VI) removal and the maximum adsorption capacity was 293.3 mg/g [15]. Heavy metal ions removal is performed via iron oxide core mesoporous silica shell nanocontainers functionalized with diethylene triamine pentaacetic acid [16]. A magnetic Fe 3 O 4 @silica-xanthan gum composite was fabricated as a hybrid adsorbent for the removal and recovery of aqueous Pb(II) heavy metal [17].…”
