Abstract
En 中文
A chemical strategy depositing functional nanoemulsions onto Fe(III)-tannic acid (TA) priming layers enables the fabrication of polyphenolic composite nanocoatings. Optimization of the composition yields stable nanoemulsions (similar to 200 nm) utilizing a 1:1 trans-cinnamaldehyde/olive oil core and a lactoferrin shell. These nanoemulsions demonstrate superior colloidal stability, specifically maintaining dispersion stability for 7 days at room temperature, resisting heat up to 60 degrees C, and withstanding centrifugal shear forces. Notably, a 3-day incubation triggers interfacial conjugation between trans-cinnamaldehyde and lactoferrin. On Fe(III)-TA-primed surfaces, these nanoemulsions promote the uniform growth of multinary composite nanofilms. This methodology offers a versatile, biocompatible approach to developing tailored composite nanocoatings, establishing a robust platform for engineering functional interfaces in food and biomedical applications.
