A state-of-the-art review on the application of various pharmaceutical nanoparticles as a promising technology in cancer treatment

Recently, rapid advancement in nanomedicine has opened new horizons towards the treatment of disparate types of cancer. Nanomedicine is considered as the science of applying nanoparticles (NPs) for various diagnostic or therapeutic aims. Nanoparticles (NPs) have attracted increasing interest all over the world for the treatment of disparate types of cancer due to their note worthy properties such as negligible toxicity and great bioactivity. The main objective of this paper is to present a comprehensive review about the potential of various NPs including silver NPs (AgNPs), gold NPs (AuNPs), selenium NPs (SeNPs), titanium oxide NPs (TiO2NPs) and iron oxide NPs (FeONPs) to treat tumoral cells, and investigate the molecular interaction at the cellular level. Moreover, different synthesis mechanisms of NPs along with their operational roles in enhancing the efficiency of conventional chemotherapeutic agents and reducing the toxicity are discussed in detail. Finally, future challenges towards the application of NPs in the field of cancer treatment are presented, and appropriate solutions to remove the ambiguities are suggested.
