Properties
Description
This specialized formulation features polyethylene glycol-modified gadopentetate dimeglumine liposomes (PEG-Gd-DTPA) engineered as a high-contrast analytical imaging model. The vesicle architecture utilizes a stable phospholipid bilayer that encapsulates the water-soluble contrast agent gadopentetate dimeglumine (Gd-DTPA) within its central aqueous core, while the outer surface is modified with covalently attached polyethylene glycol (PEG) chains to introduce a protective hydrophilic steric barrier. This configuration prevents vesicle aggregation and minimizes passive contrast agent leakage across the lipid membrane. The resulting nanoliposomes exhibit a highly uniform spherical morphology and high colloidal stability.
