A schematic illustration of immunocerasome formation. Hydrolyzed and partially polymerized cerasome-forming lipids (CFL) in acidic ethanol, cholesterol in acidic ethanol, NBD-DPPE in the mixture of ethanol and chloroform, and MAL-DSPE-PEG in chloroform were mixed and injected into PBS, creating organic-inorganic liposomal cerasomes. The polysiloxane networks formed on the surfaces of nanovesicles provide morphological stability. The maleimide-containing cerasomes were readily conjugated with thiolated anti-EGFR mAbs via maleimide-thiol coupling, forming immunocerasomes.
