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

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 incorporating Fe3O4 nanoparticles via a coprecipitation method. T
