The liposome is an ideal drug delivery carrier with characteristic lipid bilayers that resemble the cell plasma membrane and high biosecurity. They can incorporate a variety of drug candidates including anti-cancer formulations, nucleic acid and antigens. Liposomes are the most widely used carriers for delivering CRISPR/Cas9 due to their capacity to extend blood circulation time and prevent the enzymatic digestion in the serum. Besides, cationic liposomes can effectively avoid the electrostatic repulsion of negatively charged cell membranes and improve cellular uptake and endosomal escape. https://www.creative-biolabs.com/lipid-based-delivery/
