Resumen

This thesis investigates the parameters associated with the synthesis of carbon nanospheres. Carbon nanospheres were obtained through the chemical vapor deposition method, aggregated grape-like structures formed in the presence and absence of catalyst. Parameters such as temperature, flux rate, concentration, and composition of the precursor were changed throughout the experiments to control the shape and size of the nanostructures. A higher temperature and flux rate led to significant results regarding the growth of the nanospheres. Then, the material was functionalized in situ to enhance its dispersibility in polar media. The size and morphology of the nanospheres were measured by SEM and DLS while their surface modification was confirmed by FT-IR. Aggregation of carbon nanospheres resulted in clustered structures in all samples. Additionally, cytotoxicity assays were performed to study the viability of the nanospheres for lung cancer imaging. However, further investigation needs to be done for the carbon nanospheres to be applied in the medical field.
