More inter-laboratory and inter-institutions research can help overcome another issue connected with the difference in "pure" chemical, biological and medical approaches to nanotoxicology. The relatively strict division of journals into research areas, in our opinion, leads to the fact that some points are overlooked. At the same time, there is an apparent demand for multidisciplinary research, which is supported by such journals' popularity (e.g., ACS Nano). A more profound look into scientists' biography also proves that interdisciplinarity is the key factor for nanotoxicology advancement.
