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 consequences of UCNPs necessitate rigorous investigation to ensure their safe application. This review aims to provide a detailed ana

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