This laboratory study synthesized selenium nanoparticles, combined them with the enzyme lysozyme, and tested growth inhibition of two bacterial species. The combination inhibited bacteria at lower concentrations than either component alone. It is a materials and antibacterial study and does not measure selenium in foods, people or the environment.
Key numbers
- Minimum inhibitory concentration of the selenium nanoparticles against Staphylococcus aureus: 82 µg/mL; lysozyme alone: 10 mg/mL (Results, Fig. 4).
- This paper reports no numerical findings relevant to selenium dietary exposure.
Methods (brief)
Nanoparticles were made by wet chemical reduction and characterized by electron microscopy, dynamic light scattering and zeta potential, then combined with lysozyme at several ratios and tested in bacterial growth assays.
Evidence fitness
Off-topic for dietary exposure. The paper does not support dietary exposure or toxicity claims; it is context for nanomaterial applications of selenium only.
Limitations
In vitro bacterial assays only; no safety testing in animals or people; no food matrix tested.
