Phenolic acid nanoparticle formation in iron-containing aqueous solutions.
This paper presents results which show that the interaction between two phenolic acids, p-coumaric and caffeic acid, with iron results in the formation of meta-stable colloidal nano particles. The particles are characterized with dynamic light scattering and cryo-transmission electron microscopy. The results show that the nanoparticle formation is an important feature of phenolic acids which is likely to have a large impact on the behavior of these substances as well as their functionality as antioxidants.
