Based on the findings, we can propose an alternative nanotoxicology definition based on the identified keyword patterns. Nanotoxicology is an interdisciplinary branch of knowledge that studies the interaction of biomolecules, microorganisms, cells, organisms, and biogeocinosis with nanoparticle and nanofiber carriers, independent drugs, and theranostic agents in nanomedicine to reduce the risk of toxic outcomes. Some of the keywords are encountered for the first time only in 2020. These keywords are antimicrobial, autophagy, biocompatibility, caco-2 cells, cadmium, cancer therapy, chemotherapy, cisplatin, daphnia, ecotoxicity, ecotoxicology, graphene oxide, green synthesis, hyaluronic acid, nanotoxicity, nanotoxicology, peptides. We decided to focus our attention on some of these words as potential trends. We determined their relationships with other keywords in 2020 (Figure ).
