Vinblastine loaded on graphene quantum dots and its anticancer applications

Area of Science:

• Nanotechnology
• Materials Science
• Oncology

Background:

• Vinblastine is a chemotherapy drug with limitations in efficacy and side effects.
• Graphene quantum dots (GQDs) offer potential as drug delivery vehicles.
• Targeted drug delivery aims to improve cancer treatment outcomes.

Purpose of the Study:

• To develop and characterize Vinblastine-loaded Graphene Quantum Dots (GQDs-Vin) composites.
• To evaluate the enhanced cytotoxicity of GQDs-Vin composites against cancer cells.
• To assess the reduced toxicity of GQDs-Vin composites on normal cells and their in vivo anti-tumor efficacy.

Main Methods:

• GQDs-Vin composites were synthesized via homogenization.
• Characterization included FTIR, PL, UV-vis spectroscopy, and TEM.
• In vitro and in vivo studies assessed cytotoxicity and tumor inhibition.

Main Results:

• GQDs-Vin composites showed increased nanoparticle size compared to GQDs alone.
• In vitro results demonstrated enhanced Vinblastine cytotoxicity to cancer cells and reduced toxicity to normal cells.
• The GQDs-Vin (1:5) composite significantly inhibited tumor growth in vivo with no observed liver toxicity.

Conclusions:

• GQDs-Vin composites exhibit improved anticancer efficacy compared to Vinblastine alone.
• The enhanced performance suggests a synergistic effect between Vinblastine and GQDs.
• These findings support the potential of GQDs-Vin composites for anticancer applications.
