Overcoming the Mucosal Barrier: Tetraether Lipid‐Stabilized Liposomal Nanocarriers Decorated with Cell‐Penetrating Peptides Enable Oral Delivery of Vancomycin

Despite the high medical need for oral peptide delivery, instability in the gastrointestinal tract and low mucosal permeation still impede this preferred route of administration. Herein, a liposomal nanocarrier combining two self‐reliant strategies to overcome these delivery barriers is reported. This approach enables the design of a nanocarrier system with synergistic properties: tetraether lipids derived from archaea are incorporated into...
