Cancer-cell targeting and cell-specific delivery by mesoporous silica nanoparticles

Mesoporous silica nanoparticles (MSNs) have emerged as promising drug carriers. Here we highlight some recent developments related to cell-specific targeting and delivery using MSNs. Some key requirements for carrier design are discussed from a biological perspective, including a suggested experimental work-flow for the evaluation of active cell-specific targeting of nanoparticles.
