Programmable drug release using bioresponsive mesoporous silica nanoparticles for site-specific oral drug delivery

Chem Commun (Camb). 2014 May 30;50(42):5547-50. doi: 10.1039/c4cc00620h.

Abstract

Novel mesoporous silica nanoparticles (MSNs) responsive to multiple biological stimuli (pH and enzymes) were prepared through conjugation with a structure modified soy protein isolate. The particles show an extremely high pro-drug (sulfasalazine) loading with programmable drug release in simulated gastrointestinal fluid.
