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.

Monomer sequence is an emerging tool to precisely encode information (and thus structure and function) into polymer systems. Here the authors use sequence-control in complex coacervates to understand how monomer sequence translates to physical material properties.
