Synthesis and Characterization of Multifunctional Fluorescent-Magnetic Platinum Nanoclusters
There is great interest in the development of new multifunctional fluorescent-magnetic nanomaterials for use as multimodal diagnostic imaging probes and site-specific drug delivery tools. Metal nanoclusters (NCs) have been reported to possess either fluorescent or magnetic properties, but not both. In this paper, we report the synthesis and characterization of multifunctional fluorescent-magnetic Pt NCs. Our synthesized NCs (0.8 ± 0.2 nm in diameter) exhibit both bright red fluorescence (excitation: 535 nm, emission: 620 nm) and ferromagnetic behavior with hysteresis, which represents a noteworthy and significant advance in the development of Pt NCs. Our findings suggest the potential of our NCs to be applied in multimodal fluorescent-magnetic nanomaterials for biomedical applications.
