Carbon nanoparticles for gene transfection in eukaryotic cell lines

Area of Science:

• Nanotechnology
• Biotechnology
• Materials Science

Background:

• Gene therapy requires efficient and safe delivery vectors.
• Non-viral gene carriers are sought to overcome limitations of viral vectors.
• Cellulose carbon nanoparticles (CCN) are a novel class of nanomaterials.

Purpose of the Study:

• To synthesize and characterize oxygen-terminated cellulose carbon nanoparticles (CCN).
• To evaluate the efficacy and safety of CCN as a gene carrier for pIRES plasmid transfection.
• To investigate the mechanisms of action and cellular effects of CCN-DNA complexes.

Main Methods:

• Synthesis of CCN via catalytic polyaniline chemical vapor deposition.
• Characterization of CCN-plasmid interaction using zeta potential measurements.
• In vitro transfection assays in NG97, NIH-3T3, and A549 cell lines.
• Cell viability assessment using MTT and Neutral Red uptake assays.
• Metabolomic analysis of CCN-treated NG97 cells.

Main Results:

• Successful synthesis and characterization of oxygen-terminated CCN.
• Demonstrated strong interaction between CCN and pIRES plasmid (encoding GFP).
• Effective gene transfection observed in multiple cell lines, confirmed by GFP expression.
• Low cytotoxicity and minimal cellular damage observed at low nanomaterial concentrations.
• Metabolomic analysis provided insights into cellular responses and potential glioblastoma understanding.

Conclusions:

• Oxygen-terminated CCN is a promising nanomaterial for non-viral gene delivery.
• CCN exhibits good transfection efficiency with low cytotoxicity.
• The study elucidates mechanisms of action for CCN-DNA complexes in gene therapy.
• CCN holds potential for therapeutic applications, particularly in non-viral based therapy.
