WebDec 11, 2024 · The emptied RBC ghost membranes vesicles can be obtained using sonication or extrusion. Finally, the RBC membrane-derived vesicles are fused with PLGA NPs through external forces such as extrusion or sonication, which gives the hybrid NPs immune evasion properties with native cell membrane coatings. WebThe cell ghosts are produced by cell lysis and serial ultracentrifugation and have a biologically intact bilayer membrane that can be used for both active and passive targeting. Additionally, serial extrusion can give rise to cell ghosts in the 100–200 nm range (‘nanoghosts’) 21 that can be used to exploit the enhanced permeation and retention …css profile members
