Synthesis, Characterization, And Application Of Monosized Mesoporous Silica Nanoparticle-Supported Lipid Bilayers For Targeted Therapeutic Delivery To Individual Cells, Paul Durfee

Biomedical Engineering ETDs

Mesoporous silica nanoparticle (MSNP) supported-lipid bilayers, termed ‘protocells,’ represent a potentially transformative class of therapeutic and theranostic delivery vehicles. The field of targeted drug delivery poses considerable challenges that cannot be addressed with a single ‘magic bullet’. Consequently, the protocell has been designed as a modular platform composed of interchangeable biocompatible components. The mesoporous silica core can have variable size and shape to direct biodistribution and controlled pore size and surface chemistry to accommodate diverse cargos. The encapsulating supported lipid bilayer can be modified with targeting and trafficking ligands as well as polyethylene glycol (PEG) to effect selective binding, endosomal …
