Mesoporous Silica Nanoparticles: Their Projection in Nanomedicine

Figure 9

Schematic representation of MSNPs as stimuli-responsive drug delivery devices. Firstly drug is loaded into the mesopore channels. The pore openings are then closed using nanocaps to prevent premature departure of cargo. Finally, the application of a stimulus provokes the removing of the gatekeepers allowing the release of the entrapped drug.
