Nanotechnology brought various benefits to our society. Throughout the human history, many promising technologies have been disappeared due to the adverse effects on the human health and on the environment; therefore deeper understanding on the relationship between properties and toxicity of nanomaterials is required to keep utilizing the benefits of nanotechnology. Hazard of manufactured nanoparticles (MNPs) are studied through various researches; however, there are still information gaps on the toxicity induced by MNPs. Computational approaches have been widely applied to compensate experimental study, and to understand toxicity of chemicals. In toxicity of MNPs, this approach also can be beneficial to fill data gaps, and to give insights on further experimental study. Quantitative nanostructure-toxicity relationships (QNTR) are a statistical approach to correlate nanostructure with toxicity. QNTR is different from classical QSAR due to the molecular structure of NPs. In this study, structure of NP is represented by metal (Me) and metal oxide (MeOx) cluster generated from their crystal information. Descriptors for Me/MeOx NPs are calculated based on the cluster structure and metal cation information. QNTR models with the descriptors from the cluster structures show good performance to predict cytotoxicity of Me/MeOx NPs.
