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

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