The main aim of this study is to see how the different shapes and structures of carbon materials (called allotropes) influence the way their electrons behave together. The paper especially focuses on carbon nanotubes (CNTs), showing their two important uses: first, in improving X-ray technology for medical imaging, and second, as tiny carriers that can deliver drugs directly to cancer cells. For the experiments, samples of multi-walled CNTs and graphite were prepared. These were studied using different tools such as X-ray Diffraction (XRD), Angle-Dispersive X-ray Scattering (ADXRS), and Energy Dispersive X-ray Fluorescence (EDXRF). The EDXRF results showed that graphite had plasmon energy around 47 eV, while CNTs had a lower value of about 28 eV. These values match well with what theory predicts for carbon systems. Right now, CNTs can be modified to act as carriers for drugs or genes, giving a more efficient way to treat cancer by directly targeting tumors and reducing the side effects that normal treatments often cause. However, there is still no clear method to directly measure how much of the drug-loaded CNT actually reaches the tumor. This paper introduces a new approach to measure CNT-based drugs right at the tumor site. 07 08 2026 07 08 2026 21 4 https://creativecommons.org/licenses/by/4.0/deed.en_US 10.37394/232023.2026.6.4 https://wseas.com/journals/msa/2026/a08msa-004(2026).pdf Iijima, S.
