Thus, Table shows two main directions of nanotoxicology development. The first is formed by 1, 2, 3, 5, and 10 lines and is represented by countries like the USA and China. It is associated with the more active inclusion of various peptides into the composition of nanoparticles, both to target nanoparticles to the corresponding receptors of target cells and for the death of target cells or stimulation of their functional activity. The second direction is formed by 2, 6, 7, and 9 lines and is associated with the development of nanoecotoxicology. This direction relates to developing methods for testing nanoparticles' damage to ecosystems and obtaining nanoparticles with new properties using green synthesis technologies. India, China, and partly European countries can become the flagships of this trend. The third direction is associated with lines 4 and 6 and reflects the need to develop new models of chronic nanotoxicity and new models of histological barriers for nanotoxicological testing. The fourth direction is formed by lines 5 and 8 and related to new technologies and nanoparticles synthesized by nanotechnology.
