mPEG-DSPE: Additional Information
| Aspect | Details |
|---|---|
| Structure | mPEG-DSPE is an amphiphilic molecule with a hydrophobic DSPE part and a hydrophilic mPEG part. The DSPE part integrates into lipid bilayers, while the mPEG part forms a protective layer. |
| Applications | – Drug Delivery: Used in liposomes and lipid nanoparticles (LNPs) to enhance stability, prolong circulation time, and reduce immune recognition.<br>- Nanotechnology: Used for surface modification of nanoparticles to improve biocompatibility and prevent aggregation.<br>- Bioimaging: Used as a carrier for fluorescent probes in cell imaging. |
| Advantages | – Stealth Properties: The mPEG part reduces protein adsorption and immune recognition, prolonging circulation time.<br>- Biocompatibility: High biocompatibility reduces toxicity and immune reactions.<br>- Targeted Delivery: Can be modified with targeting ligands to deliver drugs to specific cells or tissues. |
| Synthesis | Prepared by esterification of mPEG with DSPE. |
