Upconversion nanoparticles (UCNPs) exhibit promising luminescent properties, rendering them valuable assets in diverse fields such as bioimaging, sensing, and therapeutics. Nevertheless, the potential toxicological consequences of UCNPs necessitate comprehensive investigation to ensure their safe utilization. This review aims to present a in-depth

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