The original research articles regarding environmental nanotoxicology address aspects that have been less explored in the nanotoxicology studies so far, such as combination toxicity and long-term toxicity of NPs. Nanotoxicology, a discipline transpired by the need to assess the human and environmental safety of nanoscale materials, has evolved over the past 15 years into a mature area of toxicology. Early on, nanotoxicology studies established a necessary understanding of dose-response relationships of nanomaterials using typical in vitro toxicology models, provided crucial information on interferences induced by nanoparticles (NPs) in the conventional toxicity assays and how to overcome these, and demonstrated that due to their unique physical-chemical properties, nanomaterials act via different toxicological mechanisms than the bulk counterparts of the same materials. The topics of the research articles and review papers address both environmental nanotoxicity as well as human health and nanomedicine safety aspects, providing an excellent overview of the current status of these important sub-areas of nanotoxicology.

Cancer is one of the major health issues with increasing incidence worldwide. In spite of the existing conventional cancer treatment techniques, the cases of cancer diagnosis and death rates are rising year by year. Thus, new approaches are required to advance the traditional ways of cancer therapy. Currently, nanomedicine, employing nanoparticles and nanocomposites, offers great promise and new opportunities to increase the efficacy of cancer treatment in combination with thermal therapy. Nanomaterials can generate and specifically enhance the heating capacity at the tumor region due to optical and magnetic properties. The mentioned unique properties of nanomaterials allow inducing the heat and destroying the cancerous cells. This paper provides an overview of the utilization of nanoparticles and nanomaterials such as magnetic iron oxide nanoparticles, nanorods, nanoshells, nanocomposites, carbon nanotubes, and other nanoparticles in the thermal ablation of tumors, demonstrating their advantages over the conventional heating methods.
