title: Nucleic acid-mesoporous silica nanoparticle conjugates for keypad lock security operation.
abstract: We fabricated a keypad lock system based on mesoporous silica nanoparticle (MSN)-nucleic acid conjugates. DNA strand displacement triggered the release of guest molecules entrapped within the pores of MSNs through logic-based control.
