Detection of melamine in infant milk powder by micro-Raman spectroscopy using biosynthesized zinc oxide nanoparticles

Zinc oxide nanoparticles (ZnO-NPs) were green synthesized using Carica papaya peel extract as a reducing agent and used to develop a novel Micro Raman Spectroscopy method to detect melamine in infant milk powder. Citrate was coated on the biosynthesized ZnO-Np, as a melamine-binding agent. SEM, AFM,...
