Proper functionalization of GO with biocompatible polymers and traditional anticancer drugs is projected for antitumor and C hepatitis treatment with better therapeutic effects and reduced side effects associated to traditional anticancer drugs (campthothecin derivatives, doxorubicin, cisplatin).

On the other hand, camptothecin is a potent antitumor agent with also known activity against hepatitis C virus, but its high toxicity, low aqueous solubility and reduced stability at physiological conditions have precluded its clinical use [7,8]. Then, two camptothecin derivatives (Irinotecan and Topotecan) are aproved by FDA for anticancer treatments, but their therapeutic efficiency is one order or lower than the parent drug [4]. Therefore, it is necessary to develop novel formulations for delivery of doxorubicin and camptothecin with better therapeutic effects achieved with lower doses and reduced side effects during chemotherapy treatments. The projected GO-biopolymer-vitamins or -testosterone composites forming nanoparticles and scaffolds for tissue engineering with a controlled release of doxorubicin and camptothecin are promising candidates for antitumor treatments.
