Summary
This study synthesized zinc and cerium-substituted magnetite nanoparticles for biomedical uses. These novel nanoparticles show promising antioxidant, anticancer, and antimicrobial properties, inhibiting oxidative stress and microbial growth effectively.
Area of Science:
- Materials Science
- Nanotechnology
- Biomedical Engineering
Background:
- Magnetite nanoparticles (MNPs) are widely used in biomedicine.
- Incorporating foreign elements into MNPs can enhance their properties.
- Zinc and cerium exhibit significant antioxidant, anticancer, and antimicrobial activities.
Purpose of the Study:
- To synthesize zinc and/or cerium-substituted magnetite nanoparticles.
- To evaluate their potential for biomedical applications.
- To investigate their antioxidant, anticancer, and antimicrobial effects.
Main Methods:
- Co-precipitation method for nanoparticle synthesis.
- Characterization using XRD, ICP-MS, XPS, DLS, zeta potential, SEM, and EDX.
- Assays for antioxidant (ROS-Glo H2O2), anticancer (MTT), and antimicrobial activity.
Main Results:
- Synthesized nanostructures exhibited promising morpho-structural characteristics.
- Demonstrated significant inhibition of oxidative stress in normal cells (2-3 fold reduction).
- Showed notable anticancer effects (2-fold decrease in tumor cell viability) and antimicrobial activity (4-6 mm inhibition zone, 1-2 mg/mL MIC).
Conclusions:
- Zinc and/or cerium-substituted magnetite nanoparticles are effective biomedical agents.
- These nanostructures hold potential for treating oxidative stress, cancer, and microbial infections.
- Further research is warranted for clinical translation.
