Myoblast cell interaction with polydopamine coated liposomes.

Area of Science:

• Biomaterials Science
• Nanotechnology
• Cell Biology

Background:

• Liposomes are versatile nanocarriers utilized in biosensing and drug delivery.
• Polymer coatings enhance liposome stability and functionality.
• Poly(dopamine) (PDA) is a versatile biomaterial formed by dopamine polymerization, offering unique properties.

Purpose of the Study:

• To characterize poly(dopamine) (PDA) coating on different liposome types.
• To evaluate the interaction of PDA-coated liposomes with myoblast cells.
• To assess the cytotoxicity of PDA-coated liposomes with and without entrapped hydrophobic cargo.

Main Methods:

• Liposome preparation with varying oleoyldopamine and dopamine hydrochloride concentrations.
• Characterization of PDA coating on liposomes.
• In vitro assessment of liposome-cell interactions (uptake/association efficiency).
• Dose-dependent cytotoxicity assays with and without entrapped thiocoraline.

Main Results:

• PDA coating characteristics were dependent on lipid bilayer composition and dopamine concentration.
• PDA-coated liposomes exhibited significant uptake/association with myoblast cells.
• Cytotoxicity of PDA-coated liposomes was dose-dependent and influenced by entrapped cargo.

Conclusions:

• PDA-coated liposomes demonstrate tunable properties for biomedical applications.
• These coated liposomes show promise for enhanced cellular interaction and controlled drug delivery.
• Poly(dopamine) coating offers a versatile strategy for functionalizing liposomes in nanomedicine.
