Effect of Zinc Oxide Nanoparticles From Infant Formula Milk Powder on Colon Cells In Vitro
Journal of Applied Toxicology, Volume 46, Issue 10, Page 3437-3445, October 2026.ABSTRACT Zinc is an essential trace element that participates in numerous metabolic processes; however, excessive exposure may interfere with the absorption of other metals, such as copper. In recent years, nanotechnology has experienced rapid growth, and zinc oxide nanoparticles (ZnO NPs) have garnered significant attention due to their versatile ...
