Cerium oxide nanoparticles were made using a mint leaf extract and tested in test-tube antioxidant and enzyme-inhibition assays related to blood sugar control. The particles, 46 to 56 nm across, showed dose-dependent activity at 500 and 1000 µg/mL.
Key numbers
- Particle diameter 46 to 56 nm (abstract).
- Effective in vitro concentrations 500 and 1000 µg/mL (abstract).
Methods (brief)
Green synthesis, characterization by UV-vis, SEM, EDX, FTIR, DLS and AFM, and in vitro antioxidant and enzyme assays.
Evidence fitness
Off-topic for dietary exposure: it concerns possible medical uses of synthesized particles and does not support dietary exposure or toxicity claims.
Limitations
Laboratory material or biomedical study; no environmental, food or human exposure measurements.
