Upconversion nanoparticles (UCNPs) exhibit exceptional luminescent properties, rendering them valuable assets in diverse fields such as bioimaging, sensing, and therapeutics. Despite this, the potential toxicological effects of UCNPs necessitate thorough investigation to ensure their safe utilization. This review aims to provide a in-depth analysis

In this study, we describe a novel strategy for the synthesis and characterization of single-carbon nanotube nanotubes (SWCNTs) modified with iron oxide nanoparticles (Fe3O4|Fe2O3|FeO). The synthesis process involves a two-step approach, first immobilizing SWCNTs onto a compatible substrate and then incorporating Fe3O4 nanoparticles via a coprecipi
