Magnesium-ion-doped silica nanosheets as degradable drug carriers with enhanced antibacterial activity and cellular uptake.

Mesoporous silica nanoparticles (MSNs) have attracted significant interest in drug delivery applications due to their good biocompatibility and high specific surface area. However, conventional MSNs typically have small pore sizes and low degradation rates, resulting in limited drug loading capacity and potential nanoparticle accumulation. This study focuses on the synthesis of novel magnesium (Mg) ion-doped silica nanoparticles (MgMSNs) using a chemical precipitation method followed by calcination.
