Abstract:
Carbon nanotubes have been explored in various fields of science and technology due to their unique properties. However, their toxic nature put limitations to its consideration for the bio-medical applications. In our work, we report the synthesis of paramagnetic CNT/Gd2O3 hybrid nanostructures through easily scalable electrochemical deposition technique. The nanostructure has shown significant longitudinal relaxivity of 18.93 mM-1s-1 for water protons indicating its possibility to be used as an MRI contrast agent. The in-vitro cytotoxicity test on the normal (HaCaT) and cancerous (HeLa) cells reveal that CNT/Gd2O3 hybrid nanostructure is bio-compatible in comparison to the pure CNTs, which is further supported by our theoretical studies using MD simulations.
