In this study, we describe a novel strategy for the synthesis and characterization of single-walled carbon nanotubes (SWCNTs) covalently attached 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 hydrothermal method. The resulting SWCNT-Fe3O4 nanocomposites were rigorously characterized using a variety of techniques, comprising transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and vibrating sample magnetometry (VSM). TEM images revealed the uniform dispersion of Fe3O4 nanoparticles on the SWCNT surface. XRD analysis confirmed the polycrystalline nature of the Fe3O4 nanoparticles, while VSM measurements demonstrated their magnetic behavior. These findings indicate that the synthesized SWCNT-Fe3O4 nanocomposites possess promising characteristics for various deployments in fields such as environmental remediation.
Carbon Quantum Dots: A Novel Approach for Enhanced Biocompatibility in SWCNT Composites
The integration of carbon quantum dots dots into single-walled carbon nanotubes (SWCNTs) composites presents a novel approach to enhance biocompatibility. These CQDs, with their { unique optical properties and inherent biodegradability, can mitigate the potential cytotoxicity associated with pristine SWCNTs.

Effect of Functionalization on the Magnetic Properties of Fe3O4 Nanoparticles Dispersed in SWCNT Matrix
The chemical properties of magnetite nanoparticles dispersed within a single-walled carbon nanotube network can be significantly altered by the introduction of functional groups. This functionalization can enhance nanoparticle distribution within the SWCNT environment, thereby affecting their overall magnetic characteristics.
For example, hydrophilic functional groups can facilitate water-based dispersion of the nanoparticles, leading to a more consistent distribution within the SWCNT matrix. Conversely, alkyl functional groups can reduce nanoparticle dispersion, potentially resulting fe3o4 in agglomeration. Furthermore, the type and number of functional groups attached to the nanoparticles can significantly influence their magnetic response, leading to changes in their coercivity, remanence, and saturation magnetization.
