Oat protein nanofibril–iron nanoparticle interface (OPN-FeNP interface)

The oat protein nanofibril–iron nanoparticle interface is a synthetic biomimetic structure developed for the efficient delivery of iron in nutritional and therapeutic applications. It consists of oat-derived protein nanofibrils, which are amyloid-like aggregates that provide a robust scaffold for the attachment and stabilization of iron nanoparticles, typically in the form of ferric oxyhydroxide (Mohammadian et al., 2019). This interface is engineered to prevent the premature oxidation and precipitation of iron, which often leads to poor absorption and unpleasant metallic tastes in conventional supplements. By providing a high density of binding sites, the nanofibrils facilitate a high iron loading capacity while maintaining the solubility of the complex under physiological conditions (Shen et al., 2017). In the context of human health, this system is primarily investigated for its potential to treat iron deficiency anemia by improving the bioavailability of iron in the digestive tract. Although it is not a traditional therapeutic target like a receptor or enzyme, the interface is a key focus of research in nanomedicine and food science for optimizing nutrient delivery.
