Summary
This study introduces a novel microemulsion method for producing solid lipid nanoparticles (SLNs) under 100 nm. The developed SLNs exhibit reduced toxicity and lower hemolytic potential, making them suitable for drug delivery applications.
Area of Science:
- Pharmaceutical Nanotechnology
- Materials Science
- Biomedical Engineering
Background:
- Microemulsion methods offer an energy-efficient approach for solid lipid nanoparticle (SLN) production.
- Limited data exists on SLN preparation using pre-screened microemulsion phase diagrams.
Purpose of the Study:
- Investigate microemulsion formation with solid lipids using hot ternary phase diagrams.
- Produce and characterize SLNs from selected microemulsions.
- Evaluate physicochemical properties, in vitro cell toxicity, and hemolysis of produced SLNs.
Main Methods:
- Screening of solid lipid phase diagrams at elevated temperatures to determine oil-in-water microemulsion regions.
- Modified hot microemulsion dilution method for SLN production.
- Characterization of SLNs: particle size, zeta potential, visual appearance, and turbidity.
- In vitro assessment of cytotoxicity on L929 mouse fibroblast cells and hemolytic potential using erythrocytes.
Main Results:
- Successful production of SLNs with particle size below 100 nm using phase diagram screening and modified dilution method.
- Evidence suggests solid lipids in produced SLNs remain in a supercooled liquid state.
- Nanoparticles demonstrated lower toxicity on L929 cells and reduced hemolytic potential compared to direct mixing methods.
Conclusions:
- The novel hot microemulsion dilution method enables controllable production of sub-100 nm SLNs.
- These SLNs exhibit favorable low toxicity and reduced hemolytic potential.
- The developed SLNs are promising for drug delivery applications.
