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

In this study, we describe a novel strategy for the synthesis and characterization of single-carbon nanotube nanotubes (SWCNTs) functionalized with iron oxide nanoparticles (Fe3O4|Fe2O3|FeO). The preparation process involves a two-step approach, first bonding SWCNTs onto a appropriate substrate and then introducing Fe3O4 nanoparticles via a copreci
