Controlling mesoporous silica-coating of layered double hydroxide nanoparticles for drug control release

Layered double hydroxide (LDH) nanoparticles (NPs) can be coated with mesoporous silica (mSiO2) to make an LDH@mSiO2 core/shell structure with the shell thickness and the pore diameter well controlled, which determines the release profile of the payload.173
