Small interfering RNA delivery by polyethylenimine-functionalised porous silicon nanoparticles.
In this study, thermally hydrocarbonised porous silicon nanoparticles (THCpSiNPs) capped with polyethylenimine (PEI) were fabricated, and their potential for small interfering RNA (siRNA) delivery was investigated in an in vitro glioblastoma model. PEI coating following siRNA loading enhanced the sustained release of siRNA, and suppressed burst release effects. The positively-charged surface im...
متن کاملGold nanoparticles encapsulated in porous carbonw
Gold was considered catalytically inactive until 1987, when Haruta and co-workers found that gold nanoclusters supported by metal oxides showed high activity toward CO oxidation even below room temperature. Since then, there has been intense interest in the use of Au nanoparticles (NPs) to catalyse a variety of reactions, including low temperature oxidation of CO, selective oxidation of alcohol...
متن کاملGold nanoparticles encapsulated in porous carbon.
Gold nanoparticles encapsulated in porous carbon spheres with high surface areas (~800 m(2) g(-1)) have been synthesized by ultrasonic spray pyrolysis (USP). The porous carbon-encapsulated gold nanoparticles exhibit excellent catalytic activity toward the reductions of both hydrophilic and hydrophobic nitroaromatics.
متن کاملMolecular Traffic Control in Porous Nanoparticles
We investigate the conditions for reactivity enhancement of catalytic processes in porous solids by use of molecular traffic control (MTC) as a function of reaction rate and grain size. With dynamic Monte-Carlo simulations, continuous-time random walk theory and solutions of the Master equation we obtain a quantitative description of the MTC effect for a network of intersecting single-file chan...
متن کاملTailoring the biodegradability of porous silicon nanoparticles.
Porous silicon nanoparticles (PSiNPs) are attractive carriers for targeted drug delivery in nanomedicine. For in vivo applications, the biodegradation property of PSiNPs provides a pathway for their safe clearance from the body. Particles sizes of 80-120 nm are of particular interest as they are important for cellular applications, such as drug delivery for cancer therapy, because these nanopar...
