Bifunctional nanomaterial Fe₃O₄@Au core-shell is a kind of nanoparticle that includes magnetic iron oxide core with gold coated. It can be used in can achieve the controllable and tunable electromagnetic fieldenhancement and may open up exciting opportunities toengineer new materialsused in biomedical applications.This research workaims at theoretical investigating the basic optical absorption property of Fe₃O₄@Au core-shell with varying number particles, inter-particle distance, and direction of incident lightusing the discrete dipole approximation method (DDA) in thewavelength of visible to near-infrared ranges of theelectromagnetic wave spectrum.The results were observed that these parameters can beenhanced optical light absorption and tuned the LSPR peak position. The obtained results might be used for basic fabricating the more performance specific applications like adrug in life science.
