Description
General Description
DSPE-Polysarcosine is a phospholipid–polypeptoid conjugate containing DSPE (1,2-distearoyl-sn-glycero-3-phosphoethanolamine, C18:0) and a hydrophilic polysarcosine chain. Polysarcosine (poly(N-methylglycine)) is a biocompatible and protein-resistant polypeptoid that serves as a promising alternative to PEG in nanomedicine and drug delivery systems.
Key Properties
- Lipid–polypeptoid conjugate
- Hydrophilic and water-soluble polysarcosine segment
- Excellent biocompatibility and low immunogenicity
- Protein-resistant and stealth surface properties
- DSPE phospholipid anchor for membrane incorporation
Applications
- Liposome and lipid nanoparticle formulation
- Stealth coating and antifouling surface engineering
- Drug delivery and nanomedicine research
- Biomaterial and hydrogel engineering
- Surface functionalization of nanoparticles
- PEG alternative delivery systems
Functional Overview
The DSPE lipid segment anchors into lipid bilayers, while the polysarcosine chain forms a hydrophilic corona that improves colloidal stability, reduces protein adsorption, and enhances circulation properties.
Summary
DSPE-Polysarcosine is a versatile stealth lipid–polypeptoid conjugate widely used in lipid nanoparticle engineering, nanomedicine, and advanced drug delivery applications.
