Zinc Phosphate Nanoparticles Produced in Saliva

Abstract

This paper reports the formation of zinc phosphate nanoparticles from the artificial digestion of zinc chloride. Initially, the formation of amorphous primary particles with a mean radius of 1.1 nm is observed, alongside the formation of larger, protein stabilized aggregates. These aggregates, with a radius of gyration of 37 nm, are observed after 5 minutes of exposure to artificial saliva and are shown to be colloidally stable for a minimum time of two weeks. The initially formed primary particles are thought to consist of amorphous zinc phos-[a] P.

Recent Progress in Synthesis and Applications of Zinc Phosphate Nanoparticles: A Review

“…Similarly, Choudhary et al [93] fabricated zinc encapsulated chitosan NPs to promote maize crop yield. In another synthesis method, Saloga et al [75] reported de novo synthesis of ZnPNPs using ZnCl2 and artificial saliva precursor through an artificial digestion process. The small angle X-ray scattering (SAXS) experiment demonstrated the formation of NPs along with larger protein stabilized aggregates within 5 min of digestion and the size of the particle was estimated to be 1.1 nm.…”

The MOUSE project: a meticulous approach for obtaining traceable, wide-range X-ray scattering information

“…The success of such a holistic approach, as well as the spectrum of its application, can be evaluated from the rich variety of an increasing number of papers to which the MOUSE has already contributed to.
