Liposome Delivery

Liposome Delivery combines traditional liposome-based drug or gene delivery systems with advanced affinity-based nanotechnology. This approach leverages the biocompatibility and versatility of liposomes—spherical vesicles composed of phospholipid bilayers—while incorporating specific affinity ligands on their surface to target particular cells or tissues. The result is a highly tailored delivery vehicle that improves targeting accuracy, payload protection, and controlled release, enhancing therapeutic efficacy and safety.

Technical Content and Mechanism

• Liposome Design and Synthesis:
  • Lipid Composition:
    Liposomes are typically composed of natural or synthetic phospholipids (e.g., phosphatidylcholine, phosphatidylethanolamine) and cholesterol. The lipid composition is chosen to optimize membrane fluidity, stability, and circulation time.
• Affinity Functionalization:
• • Optimization of Ligand Density and Orientation:
    The density and spatial arrangement of ligands on the liposome surface are carefully optimized to maximize binding to target receptors without compromising liposome stability or causing steric hindrance.
• Payload Encapsulation and Protection:
  • Encapsulation Techniques:
    Therapeutic agents—such as small-molecule drugs, nucleic acids, or proteins—are encapsulated within the aqueous core or intercalated within the lipid bilayer, depending on their solubility. Encapsulation protects the payload from degradation and controls its release.

Applications

• Targeted Drug Delivery:
  Liposome Delivery AffiNANOTECH enables the selective delivery of chemotherapeutic drugs, reducing systemic toxicity and improving drug concentration at tumor sites or inflamed tissues.
• Gene Delivery:
  Affinity-functionalized liposomes can encapsulate nucleic acids (DNA, RNA) for targeted gene therapy, enhancing transfection efficiency and reducing off-target effects.
• Vaccine Delivery:
  Liposomes loaded with antigens and adjuvants, functionalized with targeting ligands to antigen-presenting cells, can enhance immune responses and vaccine efficacy.
