文摘
- •
SnO2/porous silica/polyethyleneimine (SnO2/PS/PEI) nanoparticles were prepared by emulsion–condensation route.
- •
The SnO2/PS/PEI nanoparticles have large specific surface area and high drug storage capacity.
- •
The SnO2/PS/PEI nanoparticles display pH-responsive release and aspirin-dependent fluorescence.
