Nanoparticles made of non-noble metals such as gallium have recently\nattracted significant attention due to promising applications in UV plasmonics.\nTo date, experiments have mostly focused on solid and liquid pure gallium\nparticles immobilized on solid substrates. However, for many applications,\ncolloidal liquid-metal nanoparticle solutions are vital. Here, we\nexperimentally demonstrate strong UV plasmonic resonances of eutectic\ngallium-indium (EGaIn) liquid-metal alloy nanoparticles suspended in ethanol.\nWe rationalise experimental results through a theoretical model based on Mie\ntheory. Our results contribute to the understanding of UV plasmon resonances in\ncolloidal liquid-metal EGaIn nanoparticle suspensions. They will also enable\nfurther research into emerging applications of UV plasmonics in biomedical\nimaging, sensing, stretchable electronics, photoacoustics, and\nelectrochemistry.\n
