Mesoporous silica nanoparticle delivery of biomolecules into plants

Well dispersed mesoporous silica nanoparticles (MSNs) were synthesized and their biosafety were confirmed in the plant system. Plasmid DNA was effectively imported into plant cells using MSNs as delivery vectors. The controlled release of agrochemicals inside plants was achieved using MSN-mediated delivery system with redox-responsive gatekeepers.
