Abstract
In this study, the characterisation and composition of Fe@Au NPs were discussed. Au-coated Fe core-shell is a type of nanoparticle that contains a magnetic Fe NPs core with a fine layer of Au NPs synthesised by the micro-emulsion method. These Fe@Au NPs are characterised by Atomic Force Microscope (AFM), Scanning Electron Microscopy (SEM), High-Resolution Transmission Electron Microscopy (TEM) and UV-Visible Spectrophotometer. The best result and the smallest nanosize was obtained at a temperature of 38°C and HAuCl4.3H2O Volume 200mg. The size of Fe@Au NPs was 63.65 nm, the Fe NP’s core diameter was 32.47nm and the Au NP’s shell thickness was approximately 31.18 nm. Optimum results mention that temperature and the HAuCl4.3H2O volume play a great role in the formation of small, monodisperse Fe@Au NPs for future use as a drug delivery means to treat different types of cancer.
