The optoelectric tunability effect of structurally patterned Fe₃O₄-Au assembly on Rhodamine 6G signals under Magneto-SERS measurements.

ABSTRACT: The magneto-plasmonic tunability property of magnetite-gold complex (Fe₃O₄-Au) colloids has garnered significant interest in bio-sensory applications like surface-enhanced Raman spectroscopy (SERS). In many studies, this tunability does not only depend on the external magnetic field contribution but also on the concentration ratio between Fe₃O₄ and Au. This would require multiple preparation of Fe₃O₄-Au colloidal badges. In this study, a magnetically stimulated Fe₃O₄-Au colloidal suspension in polyvinyl alcohol was spin-coated, forming a micro-patterned thin film on a silicon wafer substrate for assessing the SERS vibrational signal response of Rhodamine 6G (R6G). The varying concentration ratio between
