18:0 PEG PE is a polyethylene glycol (PEG) conjugated phospholipid. Pegylated phospholipids are amphiphilic polymers. Nickel resin functionalization for quantum dots. It can also be used to prepare liposomes. It was also applied to cholesterol-free pegylated (CF-PEG) liposomes to study their long-term stability when loaded with the hydrophilic drug carboplatin.
