Upconversion nanoparticles (UCNPs) exhibit promising luminescent properties, rendering them valuable assets in diverse fields such as bioimaging, sensing, and therapeutics. However, the potential toxicological consequences of UCNPs necessitate comprehensive investigation to ensure their safe utiliza

In this study, we present a novel strategy for the synthesis and characterization of single-walled carbon nanotubes (SWCNTs) functionalized with iron oxide nanoparticles (Fe3O4|Fe2O3|FeO). The synthesis process involves a two-step approach, first bonding SWCNTs onto a suitable substrate and then inc
