The investigation of plasmonic Ag-Au alloy nanoparticles stands at the forefront of nanomaterial research, combining the unique optical properties of silver (Ag) and gold (Au) in a singular nanoscale entity. This abstract encapsulates the key aspects of ongoing research and the potential implications of understanding the properties of Ag-Au alloy nanoparticles. Researchers delve into the synthesis methods, exploring chemical reduction, seed-mediated growth, and advanced techniques like sonochemistry and microwave-assisted methods. Tailoring the size, composition, and morphology of Ag-Au alloy nanoparticles through precise control of reaction conditions is a focal point, allowing for the customization of their optical and catalytic characteristics. The investigation encompasses an array of characterization techniques, including transmission electron microscopy (TEM), X-ray diffraction (XRD), and UV-visible spectroscopy. These methods offer insights into the structural and optical features, enabling a comprehensive understanding of the alloy nanoparticles. Plasmonic resonance phenomena, resulting from the combination of Ag and Au components, are of particular interest due to their impact on the nanoparticles' optical responses. The applications of Ag-Au alloy nanoparticles span diverse domains, from catalysis and sensing to biomedical imaging and environmental remediation. The unique combination of properties, including tunable surface plasmon resonances and enhanced catalytic activity, positions these nanoparticles as versatile tools for addressing complex challenges in science and technology. As the investigation unfolds, the potential for Ag-Au alloy nanoparticles to catalyse innovations across various disciplines becomes increasingly evident, underscoring their significance in the nanomaterial landscape.
