WARF: P200169WO01
Inventors: Shaoqin Gong, Yuyuan Wang
The Invention
The present technology provides a nanoparticle comprising: a silica network comprising crosslinked polysiloxanes, wherein the crosslinks between polysiloxanes comprise disulfide linkages, the polysiloxanes optionally bear weakly basic functional groups, the nanoparticle comprises an exterior surface comprising surface-modifying groups attached to and surrounding the silica network, wherein the surface-modifying groups comprising polyethylene glycol (PEG), polysarcosine, polyzwitterion or combinations of two or more of thereof; and the nanoparticle has an average diameter of 15 nm to 500 nm. The nanoparticles herein may include biomolecules such as polynucleic acids, proteins, and complexes thereof, e.g., Cas9 RNP.
