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

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