DSPE-PEG 2000 is a functionalized phospholipid-polymer conjugate widely utilized to assemble stable micellar and liposomal nanocarriers for targeted drug delivery systems. Incorporating the hydrophilic polyethylene glycol head group enhances stealth properties by reducing reticuloendothelial system clearance, thereby significantly prolonging systemic circulation time and improving biocompatibility. These micellar structures undergo a characteristic phase transition from a glassy to a fluid state, modulating lipid chain mobility, monomer desorption dynamics, and overall nanoparticle stability.
