TL;DR: An MCM-41 type mesoporous silica nanosphere-based controlled-release delivery system has been synthesized and characterized using surface-derivatized cadmium sulfide nanocrystals as chemically removable caps to encapsulate several pharmaceutical drug molecules and neurotransmitters inside the organically functionalized MSN Mesoporous framework.

TL;DR: Recent research progress on the design of functional MSN materials with various mechanisms of controlled release, along with the ability to achieve zero release in the absence of stimuli, and the introduction of new characteristics to enable the use of nonselective molecules as screens for the construction of highly selective sensor systems are reviewed.

TL;DR: A honeycomb mesoporous silica nanoparticle system with 3-nm pores that can transport DNA and chemicals into isolated plant cells and intact leaves and capped the ends with gold nanoparticles to keep the molecules from leaching out is shown.

TL;DR: Mesoporous silica nanoparticles are introduced as chemically and thermally stable nanomaterials with well-defined and controllable morphology and porosity and are proposed as the basis of nanodevices for the controlled release of drugs and genes into living cells.
