Targeted intracellular delivery of hydrophobic agents using mesoporous hybrid silica nanoparticles as carrier systems

Nano Lett. 2009 Sep;9(9):3308-11. doi: 10.1021/nl901589y.

Abstract

Targeted nanoparticle-mediated intracellular delivery is demonstrated using two hydrophobic fluorophores as model drug cargo. The presented hybrid carrier system exhibits both cancer cell-targeting ability and capacity to retain a hydrophobic agent with subsequent specific release into the endosomal compartment. Furthermore, the incorporated agent is shown to be able to escape from the endosomes into the cytoplasm, making the particles promising candidates as carriers for targeted drug delivery for cancer treatment.
