چکیده

This work investigates polymeric coating of evaporated induced self-assembly (EISA) mesoprous silica nanoparticles for potential use in controlled drug release and therapeutics. As demonstrated here, lipid bilayer coatings can be easily replaced with different polymer analogs allowing for dynamic response to environmental stimuli. In addition to coupling commercially available diblock polymers we synthesized and characterized a unique dual hydrophilic pH responsive diblock copolymer, PEO-PAA. This hybrid polymeric-nanoparticle system drastically improves targeting and release capabilities through the modular ability to couple multiple different polymers. Furthermore, this work is supported by an improved method to form and study giant polymer vesicles (pGVs)

Self-assembling dual component nanoparticles with endosomal escape capability.

This study reports a novel nanoparticle system with simple and modular one-step assembly, which can respond intelligently to biologically relevant variations in pH. Importantly, these particles also show the ability to induce escape from the endosomal/lysosomal compartments of the cell, which is integral to the design of efficient polymeric delivery systems. The nanoparticles were formed by the...
