Summary
The in vivo biodistribution, pharmacokinetics, and urinary and hepatic clearance of silica nanoparticles (SiO2) with systematically varied geometries, porosities, and surface charges were investigated in healthy CD-1 mice via the intravenous injection route (i.v.). Results showed that nanoparticle porosity and surface charge played a central role in determining the biodistribution pattern of SiO2.
